What's wrong with this expression?

temp = thisComp.layer("Null 11").transform.position[0];
[temp, temp]thisComp.layer("Null 11").transform.position[1]

I try to link with the pickwip the position of X and Y of a comp to a null object and there's an error poping when I link the Y coordinate or second coordinate.

The error: Expected: ;
Error occured at line 2
Property: 'position'

I'm stuck, this is an easy one usually, but for unknown reason it doesn't work. I tried to put a ; at the end of the line 2 and still doesn't work.

You are right, I've been picking the wrong data! I needed to pickwip the word position instead. Totally forgot that *shame*

thanks!
