[FONT=Fixedsys][SIZE=1][SIZE=2][FONT=Arial]I’m a student for design and want to build myself a portfolio, showing pictures and being able to jump between fit\_to\_screen mode to actual\_pixel\_size mode. The following code is just the beginning.

I’ve wrote the code [/FONT][/SIZE][/SIZE][/FONT][FONT=Fixedsys][SIZE=1][SIZE=2][FONT=Arial]mixing some tutorials [/FONT][/SIZE][/SIZE][/FONT][FONT=Fixedsys][SIZE=1][SIZE=2][FONT=Arial](sorry, but I didn’t find a good way to clean it so it’ll be more focused) - I’m a really new about action script.

[/FONT][/SIZE][/SIZE][/FONT][FONT=Fixedsys][SIZE=1][SIZE=2][FONT=Arial] \*\*myFile \*\*is a mc waiting for an external parameter **run\_url** - a string contains something like “/projects/illustration/alice\_in\_wonderland.jpg”[/FONT][/SIZE][/SIZE][/FONT]  
[FONT=Fixedsys][SIZE=1][SIZE=2][FONT=Arial]  
You can see the \*\*trace \*\*command marked as **red**. I’d expect it to give me a number of the movie clip’s width, yet i get “ **undefined** ” - Where is my mistake?[/FONT][/SIZE]
