Show textfield as alert

hi there

When click on a button, I want to show 3 textfields in form of alert which also has ok and cancel buttons.

When clicked on ok button, i want to display the text in 3 textfields in tfMain textfield

Is this possible ???

Sorry i might have used wrong terms as i m not an expert in this.

I know this can be done in other languages but i dont know how to do in Actionscript 2

Thanks for help
