ActionScript 2.0 :: Using Dynamic Text Box Variables For PHP Email?

Passing Text Variabes to a form PHP script for emailing.If a user makes a number of selections from visual indicators on frame 1 of a Flash 8 file and textual descriptions of those selections are then actionscripted into dynamic text boxes as text values in a form on frame 2, can the text values of the dynamic text boxes be given variable names that can be sent to and processed by a server side PHP script as regular input type text box variables would be processed?

Example:
User selects 3 images on frame 1 via a mouse on(release) event.
the actionscript being:
on(release) {[code]....

On the form frame (frame 2) would be a movie clip (form_mc with instance name form) with the normal Name, Email, Message input type text boxes along with dynamic text boxes dynamicTextBox1, 2 and 3.On the form Submit button the actionscript would be:

on(release) {
var sendVar = new LoadVars ();
var receiveVar = new LoadVars ();[code]...........

Would this work? All indications I have seen through many Flash/PHP email tutorials indicate not using dynamic text boxes but components like combo boxes etc use variables and not input boxes.
