I have built a user form with a combo box, which I have the data sheet named Estimator, but I want it to populate other text boxes on the same user form when a selection is made from the combo box on the user form. I am seeking the assistance to getting the code started on the user form. I am very new to VB and am learning from tutorials and what assistance I can get from this forum. I don't completely understand how to Dim as Long, Integer, or String or what the difference is when starting to code the forms. As I said, I am that new to coding, but I am able to build the user forms just fine. I'm wanting someone to explain to me how to start the coding and help me to learn.
