@DbLookup Insufficient Argument

I’m using the following code to perform a lookup in the Notes Directory and hide data on a form accordingly:

@IsNotMember(@UserName;@DbLookup(“Notes”:“NoCache”;“85255ED1:00565AF5”;“Groups”:“Group Name”;“Members”))

This has worked for me for years. Now we’ve upgraded to 6.5 and I keep getting “Insufficient arguments for database function” as an error. I know that “key” is new in R6, but it’s also optional. Any ideas what I’m missing?

NEVERMIND! I had someone proof my formula and realized my error was in the colon.
