Cell Loses Focus When Excel VBA installed Button Clicked

I have a sub-form that focuses its answer on the active cell that was chosen. BUT, once I click on the cell/button to load/show this sub-form, my choice of the ‘active cell’ changes to the button cell and my sub-form rejects the chosen cell. I don’t have this problem if I use an ActiveX button but I’ trying to avoid them on this project. Any recommendations?
