I am having trouble incrementing a column value. The code seems basic but doesn't work.


ALTER PROCEDURE [dbo].[prc_UpdateVotes]
	@OptionID int
AS
BEGIN		

SET NOCOUNT ON;

DECLARE @NumberOfVotes int
SET		@NumberOfVotes = (SELECT Votes FROM PollOptions WHERE OptionID = @OptionID)

UPDATE  PollOptions
SET		Votes = (@NumberOfVotes + 1)
WHERE	OptionID = @OptionID

[code]UPDATE PollOptions
SET Votes = (isnull(@NumberOfVotes, 0) + 1)
WHERE OptionID = @OptionID[/code]
