Button Like Part Description on Receipt Entry

Has any one created a button to popup a box like the part description does in order entry or Receipt Entry. I would like to do this with purchasing comments on our receipt entry screen. I could also use MessageBox.Show as well im guessing.

Any help would be appreciated.


Does the entry person doing the receipt need to update/enter info? Or is this just to see comments from the PO? And does it need to be at the PO Line level? Or are PO Header comments good enough?

the user does not need to update the information it would be on the po line
