droping INDEX problem...

[TECK]

ALTER TABLE `sometable` ADD INDEX (`someid`)
any idea why i get an sql error?
to create it, i used:
ALTER TABLE `sometable` DROP INDEX (`someid`)

i also tried this way:
ALTER TABLE sometable ADD INDEX (someid)
and:
ALTER TABLE sometable DROP INDEX (someid)

[TECK]

the error i get is this:
Database error in vBulletin Control Panel 2.2.8:

Invalid SQL: ALTER TABLE sometable DROP INDEX (someid)
mysql error: You have an error in your SQL syntax near '(someid)' at line 1

i also tried:
DROP INDEX (someid) ON sometable

Database error in vBulletin Control Panel 2.2.8:

Invalid SQL: ALTER TABLE sometable DROP INDEX someid
mysql error: Can't DROP 'someid'. Check that column/key exists

ALTER TABLE sometable ADD INDEX (someid)

What Freddie posted worked for me. Just make sure what you are dropping has been INDEXed.
