Hi,

I am working on a project in Access 2003 and trying to create a validation
rule for filed in a table.

Requirement:
There are two fields -
1. Con Method - Dropdown with 6 values - A,B,C,D,E & F
2. Prime Number - Numeric field to be entered by user

Condiiton in validation rule should validate following:
If the Con Method field = C then the user must enter the Prime Number field
otherwise Prime Number field can be null.

Question to you if you can answer:
How do we implement this in validation rule for the field -> Prime Number

I was going through your turorials on webpage -
http://www.everythingaccess.com/tutorials.asp?ID=Validation-Rules
but could not get to that point.

Any help is appreciated!!

thanks,
Hasi
 
Thanks Allen. Will try this and let you know the results.

Perhaps something like this in the validation rule of the *table* (not
field):
([Con] Is Null) OR ([Con] <> "C") OR ([Prime Number] Is Not Null)

Be sure to use the table rule:
