Field Validation

[Crafty Coyote]

I am new to fileMaker and need some help with a problem. I would like to use a calculation to validate field B and if it fails display a message. My calculation is:

not(IsEmpty(field A)and IsEmpty(Field

so if they forget to place data in field B and Field A has data the message comes up.

I can't get this to work, help.

Change the validation from field A to field B. That is, validate the field the user is in. I personally never use FM's validation, but prefer my own validation messages driven by a validation script.

Do you use a plug in like eventscript?

A thing to remember when making an extra field for the evaluation purpose, to lift the checkmark i lower left corner, so the validation yell whenever it's needed.
