This is a real brain cracker for me, but I'm sure there's a way out of here..

I have a numberfield with a number, say '7'. Users can change this number with a scipt to another number (no decimals).

I need to make a calculationfield that will give a (whatever) result when the new number is not a multiplication of the original number (7).

So when number '19' is entered, I should have a result, but when '21' is entered, the calculationfield needs to be empty.

I was thinking in the direction of ranges in a globalfield, and then check the field with a PatternCount calculation, but the developmentscript took too long to make a broad range of numbers, and it's also a 'limited' solution.

Anyone.....?

I'm not sure if I understand correctly, but here goes...

In your script, set another number field (oldnumber) equal to the current number, before it's modified. Create a calculation field of Case( Mod(numberfield, oldnumber), calculation_for_result ).

Is this what you're attempting to do?

NewField = Case(Mod(Number. 7) > 0. Result, "")

Queue, thanks for thinking along!

I allready have the 'root' number (7) in a separate field. The new number is set in a -so called- 'trigger'field (exit this field and a script will run, OZ Events plugin).

But what I need to know is Case(numberfield = multiplication from rootnumber , "OK" , "")

I hope I've clearified my question by this.....

Thank you Oldfogey!

It works great!

You don't really need the > 0; if it's 0, the result will be false. Nor do you need the null result. If the test is false and the number is divisible by 7, then you won't get a result anyway. So Paul and I gave the same result; mine is just simplified a bit.

I just hadn't read your stuff properly. Yours is not only simpler it's better. Mine did not take into account the possibility of negative Mods.
