filter - With an Inner Join between just two tables, having trouble filtering a "right" database column

So say code=

select toy category, count(customerstate)
from toyinventory ti
INNER JOIN toyorders to
ON ti.orderid = to.orderid
where ti.plantid = 31-12-2020
and ti.category = 'dolls'
group by customerstate'

ok so filtering date and category which are columns in toyinventory but how to filter something from toyorders like say to.dolltype <> 'barbie' ? THX

getting cannot be bound error when i tried this as another and getting bad data when i tried this as and after ON
