1  2  3  4  5 

The above are the conditions I wrote
If a1 is checked
a2~5 is locked

If one of a2~a5 is checked
, then a1 is locked

I want to add another condition but I still can’t figure it out
That is, assuming that one of a2~5 is checked (or two, three, or four are all checked)
Then a1 Just lock it
Unless a2~5 are not checked
, a1 will be opened
