Pulling Info from components

hey guys.

im making an online store atm and its flying along to my surprise.

this is the new obstacle:

i have a set of text boxes that show a bunch of information about the product. most of them are working fine.

what im trying to do with the last one is grab the name of the file that a loader component is displaying and show it in a dynamic text box…whether it just show up or be it a variable.

any ideas?

thanks
