The "and" and "or" are complicated for alot of people.
@Mgauf - your rules are technically correct, but they will not work as intended.
The reason they are not going to work as intended is because of the way the rule is written.
Your rule 1 says if OM1 equals "something" and if OMSID equals "something" OR if OMSID equals "J979130", if OMSID ever equals "J979130", it will run the rule.
To fix it, you will have to fix the rule, the first two parts are correct, it's after the OR that needs to be fixed:
Your rule should read:
-
OM1 equals "something" AND
-
OMSID equals "number1" OR
-
OM1 equals "something" AND
-
OMSID equals "number2"
Think about it like this, AND are in parenthesis, OR are not.
So with the rule we have written, it would be (OM1 AND OMSID) OR (OM1 AND OMSID), but the rule you originally had was (OM1 AND OMSID) OR (OMSID)
It looks like the same thing for the other rule you posted as well.
Hope this helps.
