Nested IF(SEARCH)

I need a formula to accomplish the following:

Column A contains an alphanumeric string up to 50 characters in length. I need a formula to search the string in Column A for the word "Appeal" and place that word in Column B when found. Likewise for the words "Grievance" and "Complaint". If none of the three words are found in Column A, the contents of Column B should be blank.

Here's the formula I've played around with (it works on the first line but returns #VALUE! on following lines):

=IF(SEARCH("Appeal",A1),"Appeal",IF(SEARCH("Grievance",A1),"Grievance",IF(SEARCH("Complaint",A1),"Complaint","")))

I've tried entering it as an array, but that also fails.

This seems like a pretty simple problem ,but I've spent several hours trying to make the formula work so I'm obviously doing something wrong. I'd appreciate any guidance you can provide.

I've uses the following formula:

I like the following formula

as it searches within an array of full of #VALUES and and lookup has a lookup vector (range) and a result range that are connected via an OFFSET only.

Maybe something like this:

Is that something you can work with?
