Text field

here’s an easy one for you. would someone be able to tell me where to find the “text field” area for dynamic text. i’m following the advice of someone repyling to my previous plee for help, except i’m not quite flash savvy yet, and am stuck on this bit.
i’m trying to :

"go into your movieclip linkage name > ddrop

create a dynamic text field

name the text field > number_txt

where you declare your var"
