I have a form with a subform for tracking the stocks trading. I use the subform to enter new transactions. This was working fine until I have made some modifications in the design, which started giving me the trouble. Whenever I try to input any transactions by selecting a combo box in the subform, it takes me to the first record, even before completing my entries. I tried my best to solve it. But not successful. Please help ! I am attaching a sample file for reference.
