Dear @Hilary-Stoupa, Attaching files should be mandatory when one of the A1 and D4 options is selected in the System Selection section. It should not be mandatory when one of the B2 and C3 options is selected. Another issue is that when the user selects A1 from the System Selection section, module selection should be mandatory in the company info section. Can you help me on these issues?

Since this is a list form and rules are not supported on attachment controls, I don't think you'll be able to use validation rules for this. List form attachments are a little weird - they turn into URLs when the attachment is submitted. You could try hiding the ribbon and then add your own submit button and see if you can find a way to disable that if the form doesn't meet the rules you need. Another issue is that at least in the past I've found multiselects to be a little flaky - so if you select and deselect something, the deselect doesn't register. This makes validation rules on the "module" section tricky as well. You could also probably try checking for that in the submit rules.

I used a check box for each option in the System Selection section. Can you help me with the issue I mentioned above?

I added a validation rule on Module. As I mentioned - I don't know of a way to handle for required attachments in a list form. You may want to do some web searches for suggestions on that.

First of all, thank you. When I selected the A1 option in the system selection section, it became mandatory to make a selection in the Module section. However, it should become mandatory for users to select any option in the System Selection section. Could you help me with this issue as well?

I am not sure if you are saying the validation rule on Module is incorrect - or if you are saying you also need validation for the System Selection. I left the validation rule for Module, and also added validation rules for System Selection.

Firstly, thank you. However, I can send the form without selecting the system. The form should not be allowed to be sent without system selection.

Try this copy. I was checking for the fields to be blank - looks like they default to "false" instead.
