As mentioned above, my problem has been solved thanks to LarryE's suggestion to set the Tab stop to No. But I would like to ask 2 more questions.
1. The Tab stop for that button was Tab index 23. For the form to work correctly when inputting data, it only had to got to Tab index 6. What was the reason, if there is a logical answer, it jumped over all the Tab stops between 6 and landed on tab stop 23?
2. First let me state I use Microsoft 365 so all the Office programs are always kept up to date. My problem is when I was creating the control buttons on the 5 forms I wanted to, I would first click on the Use Control Wizards option and then click on the Button control. I would then paste that button into the form. Always the first time I did this it would not open the Control Wizard. I had to delete the newly created button and repeat the exact same process to get the Control Wizard to open. It would always open on the second attempt. Any idea why this consistently happened and if it could be somehow corrected?
