I have TestCase1,TestCase2 , 2 column have same value . TestCase1 list box selected value, not include in the TestCase2 listed value. TestCase2 should filter the TestCase1 select value.
just FYI , if you do want to show both listboxes as real fields rather than expressions, you could try using on select actions.
In the attached, what you select in TestCase1 will effect TestCase2 but then you can also select in TestCase2 also, not what you are after but thought it may be useful to know.
