Avoid counting blank values when apply Access formula on text data type


I use below formula in Access query column, when I copy this column data set and paste in excel, then look at the count value, it shows full count of cells in the column including blank cells. How can I modify this formula which keeps only non blank values as it should be and keep blank values as blank.

EvNum1: IIf(Left(Trim([EveNum]),2)="KK",[EveNum],"")

Hope you get my point.

You are trying to do this in Excel or Access?

In Access I generally use something like:

EvNum1: IIF(Left(Trim([EveNum] & ""), 2) = "KK", 1, 0)

Then you can simply sum that value (either in Excel or in Access).

Thanks for your suggestion Dale,

what is that & "" in the formula does?

Mark EdwardsChief Technology OfficerCommented:
TRIM() function blows up if you try to trim a Null.  The & "" both forces the value in the field to implicitly convert to a string AND converts a null to an empty string.  You aren't the first one to have problems of this sort trying to get counts.

Dale's technique is one I highly encourage you to understand and get use to using - much more accurate.
