Forum injects a space every 50 characters when tags are not used. Why anyone thought that would be a good idea is a mystery to me.
You don't say when this error occurs but I'm guessing it is when your form(s) are opened. If you are not the only one who can edit db design I'd check the object names. If the form opens, test that via the immediate window. I sometimes do this in the immediate window:
?forms!frmShipmentHdr.Name and if the reference is valid it will prove it. Then I move on to the next object in the chain (i.e. subform control). Then I'd test the name of it's source object, and so on. Don't forget that subforms load first so trying to reference anything in the main form from within subform code is likely to fail.
I've seen a few cases of where code that was never quite right fails all of a sudden because of Access updates but that's probably not the issue here. I suggest adding a newly built but simple version of your form/subform and try setting that property. You don't need all the buttons and other stuff to test if this issue is at the app level or if your form is corrupted. Importing a corrupt form into a new db is not likely to fix the corruption.
