One thought is everytime the customer selects a product, set a scratch
variable that corresponds to that category to some value like 1 or 0.  When
he selects another product, test the scratch variable for that category to
see if it has already been set from the previous action.  If it has been set
(meaning he already selected one from that category) then take appropriate
action like automatically change it or warn him that he has two from the
same category and ask him what he wants to do.
