Hi maryus,
your observation (or better assumption) is wrong.
As long as you set your button to FALSE the inner case structure in the TRUE case is not executed!
But: when you switch to TRUE case you wired the loop iterator to the inner case selector. So the inner case structure is not starting with it's first case but with the case corresponding to loop iteration count!
You can see all this by using execution highlighting!
Btw. when you have several cases in a case structure you can combine them to one case. It's all explained in the context help of the case structure! So you can combine cases (1, 3,4,6) and (2,5,7) into just one case each…
Edit: Damn, Christian was faster (with same conclusions)…
