if your movieclip has instance name mc and the textfield has instance name tf, you can use:
(its an html text)
it shows: <p aligh=....> thats all, when I put mc.tf.htmlText= ... doesnt show anything ,,,strange
then you're movieclip's not mc or your textfield's not tf or you assigned that variable before it was defined. use the trace() function to determine which problem(s) you have.
This is unbelievable... I renamed the object name to a smaller one and without capitals and it worked... AS2 maybe doesnt work so well with CS4
(and actionscript is case-sensitive.)
