Hi Bret,
I believe that YP0 and YP1 are arrays since you are using an array
(Base_Normalization) to create them. LineArray function wants its arguments
to be numbers instead. Wrapping these lines in LastValue should probably
solve the problem:
YP0 = Lastvalue( Price_Array [ XP0 ] / Base_Normalization );
YP1 = Lastvalue( Price_Array [ XP1 ] / Base_Normalization );
