I am getting the following error when I add my forst filter parameter:

Error: SQLGridSelectedView is currently unavailable.

Parm Name: wfType

Select: SELECT DISTINCT [value] FROM myTable WHERE [myField] = 'myString' ORDER BY [value]

Clause: [value] = '[Parm:wfType]'

Any help would be appreciated.
