Hi For the first calculation just use : IF(MOD(AVERAGE(D1,E1),2)<=0.34,INT(AVERAGE(D1,E1)),IF(MOD(AVERAGE(D1,E1),2)<=0.69,SUM(INT(AVERAGE(D1,E1)),0.5),ROUNDUP(AVERAGE(D1,E1),0))) Substitute the cells (D1, E1) for the new cell addresses as you go along. You may also wish to reference your targets (i.e. 0.34, 0.69) through lookups for ease of use. Cheers, Carl
