String to abbreviation - vba

Question

I'm a graphic artist, new to Excel and VBA but trying to use it to process mountains of data in excel to be used as variable data in Illustrator.
If I want to convert cells with product names for signs like "Budwieser, Bud Light & Bud Black Crown" to an abbreviation following the format "Budweiser_BL_BBC"
I have written a function that I thought would accomplish my task but it returns #VALUE!
Edit
To explain the logic: my idea was to take the string, split it on " & " and then split the first position of the resulting array on ", " then adding what was after the "&" to the end of the second array - this array, sProd, has the products separated into different positions of the array.
Then looping through that array and splitting each product at the spaces creating a jagged array.
Then loop through that array again creating a string taking only the first letter of each word in each product, separating products with an underscore. The exception being that the first word of the first product is spelled out and set in proper case. (Just saw an error in my logic and added the code for the first word exception).
Edit #2
The function should return a string with the first word of the original string set in proper case with all other words abbreviated to their first letter and products separated by underscores. So "Budweiser, Bud Light & Bud Light Lime" returns "Budweiser_BL_BLL", "All Coke & Dr Pepper Products" would return "AllC_DPP" and "Gatorade" returns "Gatorade".
This is my first bout with Excel and VBA.
Function Abbrev(p As String) As String
Dim sAmpersand() As Variant
Dim sProd() As Variant
sAmpersand = Split(p, " & ")
sProd = Split(sAmpersand(0), ", ")
sProd(UBound(sProd)) = sAmpersand(1)
Dim ProductCount As Integer
Dim ProductEnd As Integer
ProductEnd = UBound(sProd) - 1
For ProductCount = 0 To ProductEnd
sProd(ProductCount) = Split(sProd(ProductCount), " ")
ProductCount = ProductCount + 1
Next ProductCount
Dim WordCount As Integer
Dim WordEnd As Integer
WordEnd = UBound(sProd(ProductCount)) - 1
Abbrev = StrConv(sProd(0)(0), vbProperCase)
For ProductCount = 0 To ProductEnd
For WordCount = 0 To WordEnd
If ProductCount = 0 Then
WordCount = 1
End If
Abbrev = Abbrev & Left(sProd(ProductCount)(WordCount), 1)
WordCount = WordCount + 1
Next WordCount
If ProductCount + 1 < ProductEnd Then
Abbrev = Abbrev & "_"
End If
ProductCount = ProductCount + 1
Next ProductCount
End Function

Answer 1

Working code:
Function Abbrev(p As String) As String
Dim res As String, w1, w2
res = Split(Split(p, ",")(0), " ")(0)
If res = Split(p, ",")(0) Then res = res & "_"
For Each w1 In Split(Mid(Replace(p, " &", ","), Len(res) + 1), ",")
For Each w2 In Split(w1, " ")
res = res & Left(w2, 1)
Next w2
res = res & "_"
Next w1
Abbrev = IIf(Right(res, 1) <> "_", res, Left(res, Len(res) - 1))
End Function

Here's a better abbreviate function:
Function Abbreviate(Name As String) As String
Dim I As Integer
Dim sResult As String
Dim sTemp As String
I = InStr(Name, " ")
If I < 1 Then
Abbreviate = Name
Exit Function
End If
sResult = Left$(Name, I)
sTemp = Name
Do While I > 0
sTemp = Right$(sTemp, Len(sTemp) - I)
If Left$(sTemp, 1) = "(" Then
If Mid$(sTemp & "***", 3, 1) = ")" Then
sResult = sResult & " " & Left$(sTemp, 3)
Else
sResult = sResult & " " & Left$(sTemp, 1)
End If
Else
sResult = sResult & " " & Left(sTemp, 1)
End If
I = InStr(sTemp, " ")
Loop
Abbreviate = sResult
End Function

Here is a modified version to shorten up the result a bit:
Function Abbreviate(Name As String) As String
Dim I As Integer
Dim sResult As String
Dim sTemp As String
I = InStr(Name, " ")
If I < 1 Then
Abbreviate = Name
Exit Function
End If
sResult = Left$(Name, I)
sTemp = Name
Do While I > 0
sTemp = Right$(sTemp, Len(sTemp) - I)
If Left$(sTemp, 1) = "(" Then
If Mid$(sTemp & "***", 3, 1) = ")" Then
sResult = sResult & Left$(sTemp, 3)
Else
sResult = sResult & Left$(sTemp, 1)
End If
Else
sResult = sResult & Left(sTemp, 1)
End If
I = InStr(sTemp, " ")
Loop
Abbreviate = sResult
End Function
