Vector Conundrum

[Juliena]

So!

Vectors, shouldn't really be having an issue with this and yet I am. Fiddled around and came to no success, so I'm here to see if anyone understand why my script keeps yelling Syntax error at me. I'm quite befuddled. 
In short

 

vector size = <0.1, 0.1, 10.0>;
float variable = size.z;

 

Here this should return the value "10.0" under the float "variable", correct? At least, that's what I'm reading via the wiki for Vectors. Is this out of date, or are my scripts just acting up or something, because I'm very confused right now.
Any help would be appreciated!

Hard to tell without more details, but first off where are you declaring these?

You've actually solved my issue just like that

I was trying to use it before the initate state, evidentally that does not work. Moved it down into a touch_start and no more problems. So thank you! =P
