Replace Value with "If" Expression results in error

The following:

 

= Table.TransformColumns(#"Replaced Value1", {{"Location", each if Text.StartsWith([Location], "(") then Text.AfterDelimiter(_, ") ") else false, type text}})

 

results in this error:

"Expression.Error: We cannot apply field access to the type Text."

 

I cobbled this language together by using the language resulting from using the UI in the Power Query Editor.  In the screenshot below, there is some data that begins with a left paranthesis.  If data like that is identified, I want everything after the right paranthesis returned.  To keep it simple for testing purposes, I am asking that it returns "false" if it doesn't begin with a left paranthesis.

My ultimate goal would be that if it doesn't begin with a left paranthesis, that the data doesn't get transformed at all.  It just stays as-is.

Re: Replace Value with "If" Expression results in error

Just replace [Location] with underscore ("_") and you should be good to go:

 

= Table.TransformColumns(#"Replaced Value1", {{"Location", each if Text.StartsWith(_, "(") then Text.AfterDelimiter(_, ") ") else false, type text}})
