Dear xls Gurus,
I have a sheet in which 2 colimns H and J are devoted for date.
There is a code behind which enables pop up calendar for population of those dates when user press and cell.
date in column H should be smaller than date in column J.
example file:
How I can introduce a new function which will check that condition? If it is not fullfilled lets pop up a message "Error-dateJ should be >dateH"
Thanks!
