HELP! asfunction problem

How do i go about executing multipule actions with the asfunction from an external txt file (e.g: <A href=“asfunction:actions”></A>) from this setup…

(USING A MUSIC CATALOGUE AS AN EXAMPLE) I hope this makes sense

2 external txt files:
one contains a list of titles (each title acts as a button using A HREF)
one contains the track details of each title

2 dynamic textfields:
one (lets call it “titles”) contains text loaded from the titles external text file, the other (lets call it “details”) is an empty text field that recieves (or is supposed to) the track details of the pressed title.

Each of the track details has a variable assigned to it (eg:&details1=, &details2= etc) . My problem is with the syntax, and how to apply it in the function () so depending on which title is pressed, the resulting details appear in the details textfield. Also im thinking of loading corresponing swfs to each tiltle into an empty MC container as well!

My aim is script this thing in such a way as to update content & info without going into the Flash authoring enviroment.(well as much as possible)

How do i go about doing this-providing its possible
Is my set up incorrect?
What ever it is PLEASE SOMEONE HELP ME, as ive been stuck with this for weeks; and i cant progress.
