CreateTextField text location - simple question

please help me with a simple problem.

im using CreateTextField to get data from php, no problem there, but the placement of the text has be baffled.

here’s what i got:

here.CreateTextField(“t_txt”, 1, 1, 1, 10, 10);
here.t_txt.Size = 12

what i WANT is to put the text in the top middle of the movie but no matter what i change in the number it just moves to strange places in different sizes and sometimes cut in half, heres a screenshot of current one.

also, one other thing, this number basically keeps track of people in a chatroom, how can i get flash to refresh itself every few seconds to ensure it has the latest number, just have 2 frames the same and loop them?
