I can send a video to help explain. But if you go to a data entry view,
- type zero value in a few populated cells, don't press enter.
- click refresh - numbers return
- maybe click refresh again - numbers stay
- go to one of the cells, enter zero, press enter - all numbers will zero from step 1
- coloured cells for cells not submitted
- a submit button (essentially an enter)
- understand why a refresh won't work but if you press enter a few steps later your earlier entries are now in play?
