I need help with a "Does Not Contain" statement

Hi, I need help with the "does not contain" statement below.  It is entering (1) even if the line contains "spend".  I want it to enter (1) if text does not contain "Spend, spend, or SPEND".

Any help please? 

if ([#"Total"] = null
or [#"Event - Total Actual"] = 0) and [Status] = "confirmed" and [#"meeting format"] <> "Virtual" and not Text.Contains([Approver], "spend")
then 1
else [#"Total"]
