CHARINDEX doesn't work

My charindex seems to always return 0 no matter what. I tried it on
different SQL servers and I always get 0 no matter what. Here was a
test script I tried and still got zero.
DECLARE @.myvar as varchar(25)
DECLARE @.myvar2 as varchar(25)
SET @.myvar = 'hello'
SET @.myvar2 = 'll'
PRINT CHARINDEX( @.myvar, @.myvar2 )
PRINT CHARINDEX( 'test', 's' )
Both print zero... can anyone tell me what i'm doing wrong?Never mind.. I had the parameters mixed up. What a dumb mistake.|||try this, you reversed them!
DECLARE @.myvar as varchar(25)
DECLARE @.myvar2 as varchar(25)
SET @.myvar = 'hello'
SET @.myvar2 = 'll'
PRINT CHARINDEX( @.myvar2, @.myvar )
PRINT CHARINDEX( 's','test' )
