I have a loop subform named sfmLoopMess on a Form named frmMess.
Before this, I can change the data from the subform. After a few additions of combobox and stuff outsiude the subform (that I think unrelated to the subform), I can no longer edit what is inside the subform.
I attached the screenshots for better understanding.
For example, when I tried to change/add the date, nothing happen, but an error sound is heard. But I couldn't see any error message popping up.
Any idea why this happend and how to fix this?
