Lookup with XY Parameters not working properly

[felix_hofbauerJECSJ]

Hi!

I created a Block in my actual Drawing with a Lookup Parameter. In this Lookup I change  the XY-Distance Parameters and with the XY-Parameters I alter the Position of a Line and direction (angle).

My Parameter List is in german but it Basically say "Left, Right, Top, Bottom" 

Problem:

In Block Test Mode, if I choose "Unten(Bottom)" in my Lookup, my XY-Parameters somehow reset or break, I don't know what's happening in the background, and if I select a different item in the Lookup the Y-Coordinates stay "0" and are not changing to the set Value. 

What I noticed is, that in the Properties it says "Benutzerdefiniert" (user defined) and not the selected item of the Lookup.

If you want to edit the Block in the Drawing, type _bedit and select "actual drawing".

Thx for explanations!

Parameters don't like being set to 0, it really confuses them. Set it to a really small distance like 0.001 and it will work. See the image below

Thanks! It worked. I don't like the solution, but that's because of AutoCAD. It's just a shitty software...

The Zero thing came to my mind, but I wasn't sure. Haven't heard about that before, and because it worked with the X-Axis Parameter, I thought it's ok, but unfortunately not with the Y-Axis Parameter.
