Need some Help with a Addon

[Racecar]

Here is the following message that I ran. I don't know where to find the table prefix that there asking for so any help would be great. Yes, I'm new to this and learning as I go.
UPDATE (TABLE_PREFIX)vbplaza_category
SET categoryid = 9000
WHERE categoryid = 22

Run this query. (Change the (TABLE_PREFIX) to your table prefix for your vbulletin setup.)

I have run the query and don't know what to change.
Thanks.
