The OR checkbox is used to determine how a Condition Item is evaluated with the ones that follow it. Consecutive ORs are treated like a single block when evaluating and have order precedence over AND. For example, the Condition Items (A AND B OR C AND D) are evaluated as (A AND (B OR C) AND D) and not ((A AND B) OR (C AND D)). | The OR checkbox is used to determine how a Condition Item is evaluated with the ones that follow it.

For example, the expression ((A AND B) OR (C AND D)) can be represented as the list of Condition Items (A OR C AND B OR C AND A OR D AND B OR D). As described above, this evaluates as ((A OR C) AND (B OR C) AND (A OR D) AND (B OR D)) which is equivalent to the initial expression. | ||
