Dynamic Check Box

[Former Community Member]

Wondering if someone can help me. I'm not an expert at scripting but would like to know how to do the following:



I have a series of check boxes in a group, and I want to establish the first check box as a parent. When selected all the other check boxes in the group turn grey and read only.



I see the calculated read only option, but havn't got a clue what to due from there.
