Hi: I'm new to Cognos products and just installed Impromptu (User 7.0 MR1) in our lab. I'm trying to create a report from a template but can only seem to use the Blank and Simple List templates provided by Cognos samples. When using other templates, like Crosstab, when I get to "Query" screen, the OK button is always disabled. I cannot seem to activate it. What am I doing wrong in these other templates?
