How do I use while with 2 OR conditions?

Hi

I seem to not grasp how While works, I'm trying to implement a random pick without repeating the last pick so this is what I'm trying to do:

LastPick = -1

CurrentPick = -1

While:

LastPick = -1 OR

CurrentPick = LastPick

CurrentPick = RandomPick

LastPick = CurrentPick

This is the current Screenshot:

I'm sure I'm making something wrong.

I think the problem is the 1st OR between the While and the first Condition.

Maybe there is a different way to do this?

Thanks.

You should use "System compare two values" condition:

While
(LastPick=-1 | (CurrentPick=LastPick & CurrentPick=RandomPick & LastPick=CurrentPick)) equals 1

You may need to change the parentheses.

.

Another way of doing this, when you have a mix of different conditions is with a local boolean variable:
