Hi @Manish3
You seem to have missed some conditions in your description:
- What if either 1st one or the 2nd one is individually selected? What needs to be done then?
- If the 3rd one is selected, checkbox #4 will be disabled. So the 4th checkbox will never be able to be selected after selecting the 3rd checkbox.
You will be able to implement the above for 1 single run, not for multiple iterations. You need to think about all relevant conditions / combinations of selecting and disabling the checkboxes before proceeding ahead.
Cheers
