Making a query from 2 tables at same time

Hi everybody

I'm doing a two table query as follow

mhc2db=> select t1.sp, t1.pos,t2.p1, t2.p4, t2.p6, t2.p7, t2.p9 from local
as t1, precalc as t2 where t1.ce='ACIAD' and t2.idr(p1, p4, p6, p7, p9,
'HLA-DRB5*0101')>2;

and i get the following error

ERROR: schema "t2" does not exist

but those tables exists!! and are as follow!!

mhc2db=> \d precalc (t2)

Someone knows what is the problem?

Thanks
