Read loaded text

I am trying to read the text that is been dynamicly loaded into a textearea.

I get stuck on the part were a value must be “readed”
This part of code will clear my question :

on (release) {
	if (_root.hidden1.text ==  c ) {  // the hidden1 is loaded dynamicly
		_root.reactie.text = "juist";
	} else {
		_root.reactie.text = "fout";
	}
}

anyone ?
thx
