Hey guys, I’m working on a dynamic scrolling logo display, basically when the user rolls over one of the constantly scrolling logos, text appears beneath in a text field.

I have it set up like so:

**Root Timeline:**  
container\_mc  
…logoContainer\_mc (which gets duplicated and placed next to the one before it)  
…logo\_mc (where the logos are loaded into)  
…logoTitle\_txt (the textfield that displays the company name)  
…logo\_btn (the invisible button that you click to visit the homepage of that company)

So within container\_mc, logoContainer\_mc is duplicated and populated with images/text from an XML file.

\*Note: the comment “Here’s the problem”

It’s pretty straightforward, but there is some path error I can’t figure out, i need to be able to assign the textfield that corresponds to the button the user is rolling over the information from the title\_a[] array, but its returning undefined.

Help!!
