Red X for Query Result

Hey All,

I'm currently having a small issue with some query results showing a Red X. We are doing an Upgrade from 3.5 to BI 7.0, and I have taken query snapshots before and after the Upgrade. Some of the Key Figures I have in a query is showing Red X's for the values, after the Upgrade, but is fine before the Upgrade. These Key Figures are derived by using a Formula Variable.

Has someone seen this before?

Please help.

John
