Hey All - Our student records database (Access 2003) is working fine aside from this annoying, recently developed issue; we have a Form showing student records and an integrated subform showing student class records (hopefully a photo is attached). The main form works fine, we can enter new records and change old ones, however the subform seems to be locked now, buttons grayed-out, and we cannot enter or change the info. there anymore. The work-around (looking up student ID # & entering info. in another table) is a pain, so I'd like to finally solve this issue. I checked everything I could think of in the design view & do not see any obvious settings that could be the problem. In fact I compared the settings to an old 'archived' DB that works and its settings...they look the same & the archived subform operates fine (is not locked). Any help is greatly appreciated, many thanks in advance!
