vBulletin 4 Request - Looking for a Drawing/Raffle Mod

[MrFurious]

If I use this query:

SELECT user.username FROM user AS user WHERE usergroupid IN (16,103,104,105,106) OR FIND_IN_SET(16,membergroupids) OR FIND_IN_SET(103,membergroupids) FIND_IN_SET(104,membergroupids) OR FIND_IN_SET(105,membergroupids) OR FIND_IN_SET(106,membergroupids) OR ORDER BY RAND() LIMIT 1

I get this error:

An error occurred while attempting to execute your query. The following information was returned.
error number: 1064
error desc: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FIND_IN_SET(104,membergroupids) OR FIND_IN_SET(105,membergroupids) OR FIND_IN_SE' at line 1

Using this shortened version:

SELECT user.username FROM user AS user WHERE usergroupid IN (16,103,104,105,106) ORDER BY RAND() LIMIT 1

I get the following error:

An error occurred while attempting to execute your query. The following information was returned.
error number: 1146
error desc: Table 'savagesh_vBull_CMS_Prod.user' doesn't exist

Like I said, I'm not a programmer. MySQL version is 5.5.52-cll if that matters any.
