#Name? on form after requery in Access 2010 - sql

Question

I am using VBA and SQL to re-query my main form based on criteria entered in several controls on a pop up form. As far as I can tell the code is running correctly, the database is re-queried based on the criteria I enter, but 2 of my controls on my main form show as #Name? or blank after re-querying based on the criteria. Anyone know how I can fix this???
The code that runs the re-query is:
Public Sub SuperFilter()
On Error GoTo Err_AdvancedFilter_Click
Dim strSQL As String
Dim strCallNumber As String
Dim strAsgnTech As String
Dim strClientID As String
Dim strCallGroup As String
Dim strPriority As String
Dim strOpenStatus As String
If IsNull(Forms![frmTips&Tricks].txtCallNumber) = False Then
strCallNumber = " (((CallInfo.CallNumber) = forms![frmTips&Tricks].[txtCallNumber])) and "
Else
strCallNumber = ""
End If
If IsNull(Forms![frmTips&Tricks].cboAsgnTech) = False Then
strAsgnTech = " (((CallInfo.AsgnTech) = forms![frmTips&Tricks].[cboasgntech])) and "
Else
strAsgnTech = ""
End If
If IsNull(Forms![frmTips&Tricks].cboClientID) = False Then
strClientID = " (((CallInfo.ClientID) = forms![frmTips&Tricks].[cboClientID])) and "
Else
strClientID = ""
End If
If IsNull(Forms![frmTips&Tricks].cboCallGroup) = False Then
strCallGroup = " (((CallInfo.AsgnGroup) = forms![frmTips&Tricks].[cboCallGroup])) and "
Else
strCallGroup = ""
End If
If IsNull(Forms![frmTips&Tricks].cboPriority) = False Then
strPriority = " (((CallInfo.Severity) = forms![frmTips&Tricks].[cboPriority])) and "
Else
strPriority = ""
End If
If Forms![frmTips&Tricks].optOpenStatus.Value = 1 Then
strOpenStatus = " (((CallInfo.OpenStatus) = True))"
Else
strOpenStatus = " (((CallInfo.OpenStatus) is not null ))"
End If
strSQL = "SELECT CallInfo.CallNumber, CallInfo.ClientID,* " & _
"FROM dbo_HDTechs INNER JOIN ([User] INNER JOIN CallInfo ON User.ClientID = CallInfo.ClientID) ON dbo_HDTechs.TechName = CallInfo.AsgnTech " & _
"WHERE " & strCallNumber & strAsgnTech & strClientID & strCallGroup & strPriority & strOpenStatus & _
"ORDER BY CallInfo.RcvdDate;"
Form.RecordSource = strSQL
Me.cboCallNumber.RowSource = strSQL
Form.Requery
If Me.RecordsetClone.RecordCount = 0 Then
MsgBox "No Records Found: Try Diferent Criteria."
Form.RecordSource = "qryservicerequestentry"
Me.cboCallNumber.RowSource = "qryservicerequestentry"
Exit Sub
End If
Me.cmdSuperFilterOff.Visible = True
Exit Sub
Exit_cmdAdvancedFilter_Click:
Exit Sub
Err_AdvancedFilter_Click:
MsgBox Err.Description
Resume Exit_cmdAdvancedFilter_Click
End Sub
The first control in question is a combo box that displays the Client Name from the CallInfo form (Main Form).
Control Source: ClientID
And when expanded lists all available clients to select from the Users form (User ID is linked between the User form and CallInfo form).
Row Source: SELECT User.ClientID FROM [User];
After the re-query, this combobox will be blank, sometimes showing #Name? if you click on it.
The second control in question is a text box that shows the Client's phone number.
Control Source: PhoneNo
After the Re-query, this text box always displays #Name?
The third control in question is a text box that displays the clients office location.
Control Source: Location
What really baffles me is that THIS text box displays correctly after the re-query. I don't know why it would display the correct data when the Phone Number text box does not, seeing as they are so similar and work with similar data....
To Compare, the The form record source is normally based on:
SELECT CallInfo.CallNumber, CallInfo.ClientID, CallInfo.RcvdTech, CallInfo.RcvdDate, CallInfo.CloseDate, CallInfo.Classroom, CallInfo.Problem, CallInfo.CurrentStatus, CallInfo.Resolution, CallInfo.Severity, CallInfo.OpenStatus, CallInfo.AsgnTech, dbo_HDTechs.Email, CallInfo.FullName, CallInfo.AsgnGroup, User.Location, User.PhoneNo, CallInfo.OpenStatus
FROM dbo_HDTechs INNER JOIN ([User] INNER JOIN CallInfo ON User.ClientID = CallInfo.ClientID) ON dbo_HDTechs.TechName = CallInfo.AsgnTech
WHERE (((CallInfo.OpenStatus)=True))
ORDER BY CallInfo.RcvdDate;

Answer 1

Just going on what you wrote, I may take a slightly different approach (just personal preference).
I would change all of your 'IsNull' tests to also check for 'Empty'. i.e.
If IsNull(Forms![frmTips&Tricks].cboClientID) = False AND ...cliientID <> ""
Just today I had an issue relating to form references in a query WHERE clause, so I changed to:
strClientID = " (((CallInfo.ClientID) = '" & forms![frmTips&Tricks].[cboClientID] & "')) and"
Add a Debug.Print of your generated SQL, then look at it and try to run that SQL manually
Good Luck,

Answer 2

Solved by designating the form in the control source like: CallInfo.ClientID
I still don't know why the Client Office displayed Correctly... Anybody have a hint? :)
