couple of field calculations...

[melanemac]

I need to create some calculations.

I have some fields that are calculating a number (see below) * a percentage. Some records may not have the number, so they are coming out as #Error in that calculation, which is fine to me (this is a multi-step query).

Field1 Field2 Field3 Field4
10 5 10 10
4 3 3

As part of the second step, I want to then take an average of the numbers in Fields1-4 and create a new Field. How do I do this? I currently have made a table with the final step of multiplication calculations above, which eliminates the #Error values. However, I can't seem to take an average of the fields if one of the fields is blank.

Any help would be much appreciated.

use nz

nz(mynullfield, 0)

Sets the value to zero in case your field is null.

Thanks.
That worked for the null field, but I would like to try and take the "Make Table" out of the equation.

Is it possible to do a count on the fields if one of the fields is #ERROR?
I have tried the ISNUMERIC and ISERROR and I can't seem to get them to work.

My queries start as follows:
1. Pull Salary
SM1 25A: IIf([total bm file - step 1]!pay_grade>"12",([Total BM FILE - STEP 1]![SM1 25]*[CREATE ACTUAL AGING FACTOR]![Actual Aging Factor]),([Total BM FILE - STEP 1]![SM1 25]*[CREATE ACTUAL AGING FACTOR]![Actual Aging Factor]*[geographic adjustments]![adjust percent]))
The problem lies in that if one of the fields that is linked to this query is empty, then the calculation comes out as #ERROR.

2. Count SM1 25A, SM2 25A, SM3 25A, SM4 25A
The only way I could find around the #ERROR issue, was to create a Make Table from 2 above and then the fields are null.

Any suggestions?
Thanks!
