Need Help On set analysis

[qlik4asif]

I want to find the Manufacturers whose sales are over 100,000 for the 2 categories CHEESE CAKE and ACC in January 2013 (period P01/13). But I want to remove from that list those whose sales are lower than 50,000 for all categories in January 2012:   

write set analysis code for this

I tried with this

Only({<Sales={">100000"},categories={'CHEESE CAKE' ,'ACC' },period={'P01/13'}>-<Sales={"<50000"},categories={*},Period={'P01/12' } >Manufacturers})

Can some one correct this expression.

Thanks in advance
