Add "Contains" and "Does Not Contain" conditions to If...Then Statement in Keyword testing

Thank you, cunderw.  I got it now.  I see how this will do what I want. 

I'm hoping you can help shed some light on how I am using this.  I am trying to have a "or" in my Value but failing miserably. 

What I am trying to do is look at a specific value on a spreadsheet (Dental Children) to see if the Value = "add dependent" OR "add one dependent"exists and based on that do a specific thing.  Here is what I have:

Property = ProjectSuite.Variables.EmpData("Dental Children")

Condition = cmpEqual

Value = "add dependent" or "add one dependent"

Case Sensitive = 0 (no?)

I'm pretty sure the problem is syntax related in the Value field. 

I've also tried making it a code expression:

ProjectSuite.Variables.EmpData.Value("Dental Children") == "add dependent" || ProjectSuite.Variables.EmpData.Value("Dental Children") == "add one dependent" 

but that also fails.

Any thoughts on how to best approach this?
