Position movie dynamically

hi iwas wanting to know if this is possible and if so how. i have a dynamic text field that loads a variable into it (just a simple text file). this text file will be updated on occasion. i also have a movie clip to be positioned below the text field, however i want the movie clip to change position depending on how much text is in the text field so there isnt a large gap and so they dont overlap. is this possible? i tried the following actionscript to adjust the size of the text field depending on the amount of text.
textField2.autosize = “center”;
however i have no idea how to get the y position of the movie clip to adjust accordingly.
