I have a field with radio buttons from a value list, The values are 1, 2 and 3. What i want is when 2 is selected, an other field in the layout can't be empty, if 1 or 3 is selected the field is allowed to be empty.

The script/Calculation has to work in the web publishing engine (browser)

Try a validation on your other field of radioButtonField <> 2 or not IsEmpty(thisfield).

It won't work. I think i have to be more specifik. (sorry)

I have a field with radio buttons from a value list, The values are Standard, Unterbau and Skum.

What i want is when Unterbau is selected, a field called Unterbau Shore can't be empty.

if Standard or Skum is selected the field is allowed to be empty.

radioButtonField <> "Unterbau" or not IsEmpty(Unterbau Shore)

Make sure the validation is on Unterbau Shore.

It won't work.

I make the validation in Define Database, and on the specifik field.

any ideas?

It works fine for me. Check that 'Validate only if field has been modified' is deselected.

That was it

Thank you for taking your time
