i'm running a project with form "postleave" and "timerem".. when i run the form "post leave" after running form "timerem" i get this error..

Error loading file - record number 9. CREATEDTR < or one of its member>. Loading form or the data environment : Variable 'EDATE' is not found

after i close my project, and run it again.. this time running form "post leave".. i don't get any error..

i'm sure there's not variable 'EDATE' in form "postleave"..

what does that error means?
