Hi guys,

Can someone please tell me or explain what does the -1 do in the below condition

=IIf([chkBranch]=(-1),[cmbForBranch],IIf([chkPostalCode]=(-1),[cmbSelectCUIC],IIf([chkCUIC]=(-1),
[List107])))



Thanks in Advance!

The "-1" is the boolean equivalent of "True". For a check box, it would mean return the records which are checked.
