Suggestions Please: After using Lookup the stretch isn't working properly.

I have a look up Perameter with two options: "90 Degree" & "Straight". When straight everything is working as intended. When I apply the 90 Degree Lookup perameter the stretch actions are not working correctly. I Understand why it isn't workinng, but I don't know which direction I need to go to get this to work.

e.g. 1 - After the Lookup "90 Degree" is applied the Distance2 should lengthen the "6x16x10'" dimension as it would when it is straight.

e.g. 2 - After the Lookup "90 Degree" is applied the Distance1 should strech everything, up or down, equaly. This is different than when the Lookup is "Striaght".
