Wicked Variable Problem

Hello everyone. I would greatly appreciate some help on this variable problem i am having. I love Flash but am fairly new to using actionscript. I am setting up a proposal system for my company where teh secretary will only have to alter the .txt files to produce a sales proposal. Therefore, everything I do has to be done without her having to open flash other than to simply Publish. To do this, I have set up two external text files:

1). Loads a bunch of customer, salesman, and product option variables (including price,option, etc)

2). Loads a batch of special “descriptions” (approx. 75 of these in paragraph form) with variable names P1 through P75.

I will only use 5 of these descriptions in the movie but it will change upon each use. My idea is to have a variable in the first text file that will call a specific description from the second text file. As you know, when I perform the loadVariables off the text files I cannot just assign description1 to equal my variable in the second text box.
(Example-- &description1=P10&)

So far my dynamic text box just reads P10.

How can I convert the P10 from a string to a variable name that matches one of teh descriptions to send the appropriate paragraph to a dynamic text box?

Thanks for your help, look forward to the what people can come up with.
