I created a parametric HDPE reducer. The strange thing is it seem everything work finely in family editor, however it start creating error every time i change the size of the smaller diameter pipe(ie from original 63mm/50mm change to 63mm/32), but it wont happen when i change the size of the larger diameter pipe (i.e from original 63mm/50mm change to 75mm/50mm).

I think its to do with size reversal.
63 ->32 works but 32->63 doesn't.
You need to include both options in your lookup table, or you need a formula which says "if Nominal Diameter 1 is bigger than Nominal Diameter 2 then ND1 equals Nominal Diameter 1, otherwise equals Nominal Diameter 2" so that ND1 is always the bigger end. You then need a similar formula to make ND2 the smaller of the two. Then use ND1 and ND2 in your lookup table formula.
At least I think that's the problem.
