I'm using VFP 7.0

Most of the time that I try to build an exe from the Project Manager I get an error "variable 'fm_Formation' not found".

fm_Formation is the name of a field in one of the tables that are being included in the app. It has a candidate index on the field.
If I exclude the table from the app, then it builds fine, but when I include it again sometimes it builds, sometimes not.

TIA
