Looping through external variables [AS 2]

programming flash
1

Hey peeps,
I’m going bananas over here! Please help!
I’m using LoadVars (results_lv below) to load variables from an ASP page, returned as follows:
option1=4&option2=5&option3=32&option4=… etc. etc.

There are a different number of “options” returned each time, depending on the query sent to the script. I have access to the number of options ahead of time, but still don’t know how to loop through them…

So… How on earth do I loop through these variables?!?
Basically I’d be thrilled to be able to do this:

trace(results_lv.option1);
trace(results_lv.option2);
trace(results_lv.option3);

and so on, until they’ve all been traced.

Thanks in advance to anyone who can help me.
Steve
