I used to remember how to do this when I used Access97 but I have forgotton. I am currently trying to learn Access2007 and I am about to pull out what remaining hairs I have left. Here's the info. I have a form InvInputfrm that has a combo62. When I select the value in that combobox I want it to be the parameter for my select query. This result will then populate combo64 of the InvInputfrm. Then based on the selection of combo64 a textbox will be filled in with data from column (1) of that combobox. Any assistance that you can give would be greatly appreciated.
