update checkbox value according to other checkbox value

[Dominik Mueller]

Hi,

I'm using script runner and I need to update checkboxes value according to another checkboxes value to keep them in sync.

Example:

Checkboxes Field Name: "Requested instance"

possible values: "A", "B", "C"

If A is true, B need to be set to true automatically and vice versa.

Can anybody help me with this?

Thank you :-)
