Simple Expression Error, why ??

[Dan Ebberts]

A variable name can’t have a space in it. Try it this way:

var blueCircle = thisComp.layer(“BlueCircle”).transform.rotation

As far as I know there’s no way to change the font size in the expression editor.

I want to assign a variable on the Red Circle for the Blue Circle and removing the space continues After Effects to fire back an error:

That error is:

After Effects warning: Undefined value used in expression. Could be an out of range array subscript ?

Error occurred a line 0.
Comp: ‘Comp 1’
Layer 2: (‘Red Circle’)
Property: ‘Position’

var bluecircle=thisComp.layer("BlueCircle").transform.rotation

Either of these seem to work:

var bluecircle = thisComp.layer(“BlueCircle”).transform.rotation;
bluecircle

Or,

bluecircle = thisComp.layer(“BlueCircle”).transform.rotation

It’s not working, same error.

[Dan Ebberts]

Well, I’m stumped. Both versions that I posted work for me, while the version you posted generates the error you described. Apparently you can’t end an expression with a var declaration (I guess I’d never tried it before) but if the versions I posted (which don’t do that) generate the same error for you, I have no idea what’s going on.

If something as simple as that, doesn’t work I’m not going to try anything else. I wanted to stay with CS3 Maybe I should scratch things together and upgrade.

I got the expression to work, it is quite sensitive it more so then the JavaScript language its self. I’m going to have to do some more practices so I know what arrangement the syntax has to be in.

[Dan Ebberts]

I’m really curious – what did you have to do to get it to work?

I thought I got it to work. Argh!
