    Access 2010 division by 0 error

    Hi, I have got a div by 0 problem which I've tried to get round by using an IIf statement with no luck. It's in an aggregate query grid, the formula is in "expression" mode and is:


    I've tried Iif (([b3]=0,"",...... but no luck.

    Can anyone tell me what I'm doing wrong? Thanks so much

    First, is this in a query or behind a form or report? Since you are attempting to use the Immediate If function, I will presume it is in a query. In that case, the syntax should be something like Sum([I3] * IIF(Nz([B3],0)=0,0,[DirectHours]/[B3])) - note that is untested aircode - but the idea is to deal not only with the 0 case, but also with the case where [B3] is null. That uses the Nz() function to return a 0 if it is null.
