Hello.<br><br>I had posted a similar question, but I am still stuck, so I will make my question more exact:<br><br>I have a form called "Contacts" and in this form is a subform called "Problems and Solutions subform." There is a combo box in my sub-form called "Problem Category" which is based on a table full of problem categories. Now, I have a second combo box called "Sub-category" which should display values from one of many tables based based on the problem category chosen.<br><br>Since I have 18 categories, I have 18 associated tables. I have had some suggestions to try a query, but I have not had success with this. About all I could do was get it to show the same table no matter what category was selected. I tried to put all the sub-category tables in the query and use the build button for each table to no avail (I get no selections in this case). It would seem as if the query is ANDing when it should be ORing. <br><br>Right now, there are no relationships except the sub-form's table has a value for the problem categories and sub-category which are look-up tables to their respective tables. The sub-categories table is blank.<br><br>Aargh, this would be a lot easier to explain if I could send some screen captures. So, if someone is willing to work with me over email, I could provide them. Otherwise, I hope this has made some sense.<br><br>Thanks and Regards,<br><br>--Dan
