string functions

whenever i used instr() or left() right() mid() etc, i get a "invalid procedure call"

no idea whats going on...

VB Code:

For i = 0 To Len(strSource) Step 1
        If Mid(strSource, i, 1) = Left(strSearch, 1) Then
            For j = 0 To Len(strSearch) Step 1
            
            Debug.Print j + i
            Debug.Print Mid(strSource, j + i, 1)
            Debug.Print Mid(strSearch, j, 1)
            
                If Mid(strSource, j + i, 1) <> Mid(strSearch, j, 1) Then
                    isitthere = False
                End If
                
                If j = Len(strSearch) Then
                    isitthere = True
                End If
                
            Next j
        End If
    Next i

id use instr() but i keep getting errors with that, and now i get errors with mid() and left()

:confused:
