Could you post the demo directly in the forum? Code posted on file sharing sites will be gone some day, and users seeing this thread in the future will not benefit from a solution.
In order to attach code to a forum post put all required files into a common zip which you can upload under "Attachments and other options" below the edit field of the message editor. Please do not add the exe and other compiler generated files, otherwise the zip will be too large. Add only .pas, .lfm, .lpi, and .lpr files as well as required data files (database file, Excel file).
I did look into you file hoster upload already, and saw that the gdb file may be too large. Please delete as many records as possible, or create a dummy file in a way that the bug is still visible.
Sorry, I have to insist on having the compilable project here in the forum.
