Dynamic text talking to buttons

Hello people

I’v been creating a little question and answer game, where a randome quote from an external file pop’s up and then you have two buttons as possible answers, The randome quots are in a text file that looks like this

quote1=blah blah blah blah blah&quote2=blah blah blah blah blah blah&quote3=blah blah blah blah blah

now what i would like help with is this… is it possible for me to put some script on the buttons that 1st has a set of quote numbers and when pressed looks at the dynamic text box to check if it has loaded a quote assigned to it!

this is the random script on the time line

ranQuote = new LoadVars();
ranQuote.onLoad = function(success) {
if (success) {
RanNum = Math.ceil(Math.random()*10);
ran = this[“quote”+RanNum];
quote_txt.text = ran;
else {
quote_txt.text = “The text failed to load due to an error”;
