DCount, how do I have multiple conditions

Dear All,

I have a problem, I have a report which runs off a few queries.

Instead of creating 14 more queries I thought to use the DCount Function to enable me to use the queries to the best of my ability.
That worked fine when I used:

CODE

=DCount("REFVAL","SrNoiseCmplCount","[SRNOICAT]='INDUST'")
The above worked fine when I only had to look for catefories.

I then needed to count via categories and outcomes.

This opened a can of worms, because I can have categories without outcomes.

I tried the DCount function as below and it gave me an #Error

CODE

=DCount("REFVAL","SrNoiseOutCome","IIf([SRNOIOUT]='NUICEA',IIf([SRNOICAT]='INDUST'),0)")
How do I use DCount to set multiple criteria?

Thank you for your forthcoming help smile

Thank you,

Kind regards

Hi,
I looked in the help file and found an example that helped and I used it in my problem...

But it gives the total number in the query 168 rather that 0 which is what this would give if you entered the criteria in the query

CODE

=DCount("REFVAL","SrNoiseOutCome","[SRNOIOUT]='NUICEA'" And "[SRNOICAT]='INDUST'")

Any help would be greatly appreciatedbigsmile

Thank you,

Kind regards

I have figured it out yay!

The CORRECT CODE is below.

CODE

=DCount("REFVAL","SrNoiseOutCome","[SRNOICAT]='INDUST' And [SRNOIOUT]='NUICEA'")

INCORRECT CODE:

CODE

DCount("REFVAL","SrNoiseOutCome","[SRNOIOUT]='INDUST'" And "[SRNOICAT]='NUICEA'")
YAY! bigsmile

Thank you,

Kind regards
