We support a small number of simple functions designed to make your life easier.
=WSGBPA(B1,CAD) for instance does a GBP Average conversion from CAD. There are others which use the Period End rates, or for conversion into USD.
In =IF(WSYEAR()>2000,B1+C1,0) our function WSYEAR gets the Year of Account for a board's scope.
That's about it. There, that wasn't difficult.
