Error checking for NULL in VBScript, getting “Object Required”

Question

From your code, it looks like provider is a variant or some other variable, and not an object.

Is Nothing is for objects only, yet later you say it’s a value that should either be NULL or NOT NULL, which would be handled by IsNull.

Try using:

If Not IsNull(provider) Then 
    url = url & "&provider=" & provider 
End if

Alternately, if that doesn’t work, try:

If provider <> "" Then 
    url = url & "&provider=" & provider 
End if
