Hi, I have 3 products 1, 2, and 3, each of them contain several elements a, b c, d. Each product has different specification depending on the elements % Product 1: a1<a<a2, b1<b<b2, c1<c<c2 Product 2: a3<a<a4, b3<b<b4, d3<d<d4 product 3: a5<a<a6, b5<b<b6, c5<c<c6, d5<d<d6 I would like to have a list Product , a, b, c, d, In_Spec I would like to use eval to assign the value to In_Spec |eval In_Spec=( if Product=1 and a1<a<a2 and b1<b<b2 and c1<c<c2, "yes", "no") but How can include product 2 and product 2? In the end I want sth like: |eval In_Spec=( if Product 1.......... Product2........... Product 3............"yes", "no") can someone help me with that? Many thanks in advance!
