I am having trouble with my subform. It Contains three objects a combo box where I can choose my class from a table, another combo box where I select a month on a list that I have typed in, and the third is a control box where I just type the year in. The subform lists all my options, but I cannot choose any and the text box won't except and input. I had it working yesterday but when I come back to it today that is when I started having problems. I have deleted the subform and started over 3 times. I have also deleted the combo boxes and started over with them also.
