First of all, thank you VERY much for all the help so far.
Ok, I've got the event handler working with the locked cells. Perfect.
As for the other code, I've been able to get it to run when I added it to the class module and a standard module (editing the line you indicated). That being said, it's worked like a charm now!
The only thing I need is to move the spinner into the cell. Currently it's out of the cell on the right hand side of it... I just want to move it from outside the cell into the cell.
Thank you so much!
