run time error 3061 - ms access - vba

Question

I am relatively new to MS Access and VBA. I am trying to do a bit of code for this DB and get error message 'Run Time Error 3061. Too Few parameters. Expected 1" when it gets to the OpenRecordSet clause.
I have been researching and looking at this for days but cannot figure out the reason for the error. I know the error is in the SELECT specifically in the WHERE clause when the form is being closed.
The strange thing is that when i change the condition to Record_Num = 2 or any specific number it seems to work, but i need to use the Record_Match_Temp variable.
Any help will be appreciated. Thanks in advance. Here is the code
Option Compare Database
Dim Record_Match_Temp As Integer
Dim Logged_Now As String
Private Sub Form_Close()
Dim db2 As Database
Dim rs2 As Recordset2
Dim SelStr As String
Set db2 = CurrentDb()
SelStr = "SELECT Record_Num FROM User_Log WHERE Record_Num = Record_Match_Temp"
Set rs2 = db2.OpenRecordset(SelStr)
End Sub
Private Sub Form_Load()
Form_User_Name = Environ("UserName")
Logged_Now = Now()
Dim db As Database
Dim rs As Recordset
Set db = CurrentDb()
Set rs = db.OpenRecordset("Select * from [User_Log]")
rs.AddNew
rs![Log_User_Name] = Environ("UserName")
rs![Logged_Computer] = Environ("ComputerName")
rs![Logged_In] = Logged_Now
rs![Record_Match] = rs![Record_Num]
Record_Match_Temp = rs![Record_Num]
' rs![Logged_Out] = Now()
rs.Update
End Sub
Private Sub Form_Timer()
Date_Time.Requery
End Sub

Answer 1

SelStr = "SELECT Record_Num FROM User_Log WHERE Record_Num = " & _
Record_Match_Temp
Add single quotes around Record_Match_Temp if the field is not numeric.
