Thanks Greg

I tried run it on both Entry and Exit same time and this gave me a runtime error ! And when I leave it as it is to run OnEntry only, all is working fine ! I tested and did uncheck some boxes and the tally would update correctly without a problem !

Thanks for the code update but there is one problem with the message box. It pops up with each check click and this isn't practical. It would be great if the message would instead display in a text field next to the Tally in each group (I created a text field called grp#Message next to each tally). This way, it would be there always and without any repeated popups.

Thanks so much for your great help and patience
