"And" and "Or" troubles within an IF statement

I'm trying to use "And"& "Or" within an If statement. I probably have my syntax wrong.

the result comes back false when the data should make it true. Here is the code:

ElseIf (origNum = "006260006" Or origNum = "30062600006") And creditOrDebit = "D" Then'do things hereEnd If

-When I debug and come to this line it hops over it and doesn't enter in.

-origNum actually equals "006260006" and creditOrDebit = "D".

-so I'm assuming my "Or" statement isn't working.

-Hopefully this is a quick easy question. Thanks!
