syntax error in a trigger. can't find it.

Greetings,

I must be very tired, very hungry or both. I'm getting a syntax error in
the last line with the 'END;' But am clearly not seeing what the error is.
Any help would be appreciated.

if (lrec.rqst_delivery_time + '2.5 hours'::interval)::time > '16:40'::time
AND extract('dow' from (lrec.rqst_delivery_time + '24 hours'::interval))
