What is wrong with this code?

1

Hello!
I am trying, this time, to create a scroll area text. Where after pressing a button, a text will be added to the textarea below the previous text.
Although, dont know why, its not working.

i am using this code to add the text to the textarea and then trying to scroll down and add more text bellow the previous one.
where m_text is the name of my text area.

I have also attached the file.

Thanks alot.
Cheers.
leo.


 
on(release)
{
 m_text.scroll = m_text.scroll +1;
 m_text.text ="hello  ";
}
