I feel REALLY stupid for asking this, as I'm sure the answer is right in front of me, but for the life of me I can't figure this out.

How do I properly code up nested arguments for an "if" statement?

Example: two variables "varA" and "varB" have been assigned their values. I want to check what those values are before acting on the rest of the script: specifically, "varA" should be some value "foo" AND "varB" should be neither "bar" or "baz".

Here's how I thought it should go:

if (varA == "foo") && ( (varB != "bar") || (varB != "baz") )
{
do something;
}

When I do this, though, it seems to ignore the "varB" stuff and only acts on all instances where "varA" is "foo". The problem must be in how I nest the "varB" conditions, since if I remove one of them and fix the parenthesis accordingly, it works for that value of "varB". I have no idea how to make it work for my needs, however.

Thanks for y'alls input.


EDIT: Figured it out. Boolean fail on my end >|
