Running Control Variable

[Mamona]

hi
I am running A GARCH(1,1) model for causality in Variance. I have two series (y1,y2,.....,N), (x1,x2,.....,N) where N=99
and
scalar ind=1
scalar n=5
While running for control variables
for !a=1 to 99
I got the following Error message
For statement is unterminated in for !a=1 to 99.
I REALLY DON'T KNOW whether I am doing is right?
AS I am beginner in coding. i used to do through clicks before.
Can someone please correct me where I am making mistake?

Thanks

Just saw this one...you'll need a matching "next" statement.
