how touse lookups

[mehdii]

I try to link two variables Nda and Of in my model by a lookup function, ce. In the sketch editor I have linked these variables but when trying to write an equation for the lookup function ce I face difficulty. I used lookup as grapgh that gives me a set of pair numbers. However, I cannot put Nda as input to the CE. I Wonder if someone could help.
