hi can I get advice on some VBA scripting that will stop a sheet from closing under these circumstances:

data is entered into a cell under a column call incidents - 3 other cells should also be filled out to complete
the collection of data for the incident. some staff are not filling the 3 other cells just the main incident
column cell and our data collection is incomplete. can we stop the sheet from closing if data exists in
the incident column cell but not in the other 3 cells and then once data is entered the sheet can close off?

cheers
