I am receiving the error "wrong number of arguments" when I try to call a
function from a text box.  I am trying to put =BuildCriteria() in the contol
source.  

The function it is calling is on the form and is as follows:

************************
Public Function BuildCriteria() As String

If Len(Me.CurrAuditor) > 0 Then
   BuildCriteria = BuildCriteria & Me.CurrAuditor
End If

If Len(Me.VendorName) > 0 Then
   BuildCriteria = BuildCriteria & Me.VendorName
End If

If Len(Me.Platform) > 0 Then
   Build Criteria = BuildCriteria & Me.Platform
End If

End Function
************************
I've used this function sucessfully in other places so I am not sure where I
am having an issue.

Thanks!
