I have been running the same code for an HMI screen using Excel for some time now and now that I am ready to put it out to Field use, I get a pop up message when pressing a button. The error is Visual Basic error 400.
If the sheet is not protected then there is no message box. The code still works but the pop up is a nuisance. Anyone tell me what is error 400? Or how can I block it?
