Option Button

What am I doing wrong?

I want the option buttons to trigger a command.

(defun c:FindMS_T/Form1/OptionList1#OnSelChanged (ItemIndexOrCount Value /)

  (cond

    ((= uOpt 0)(command "_IsolateObjects" "P" ""))

    ((= uOpt 1)(command "_UnisolateObjects"))

    );cond

)

You can try changing the form's {2} to 1. See the last paragraph on this page:
{2}

I just double checked and it is set to 1.

Hi, I had a test with you lisp and project file. But both files do not belong together. I had some search & replace but it still not show without errors. So I stop testing.
With regards, Fred
