[Flash 8]Figuring out total height of attached MCs

1

This may sound a bit redundant if you read my other post today about text, but i have another question regarding this scrollpane thing. So, again I have a movieclip called “entry” with textfileds (basically it’s just a header bar and a bottom border bar with two textfields). This is dynamically attached based on the number of xml nodes into a holder clip.

My question is, can i figure out the total height of the attached entry clips? The scrollpane i have so far scrolls to a fixed height of the holder clip and i want it to scroll to the height of the attached entry clips.

Possible?

Thanks again for the help. :slight_smile:

Here is all the code so far:
