For instance, for you building 1A, assuming it's a button, put this code on it:

Actionscript Code:
on(press){
    name_textfield.text = name[0];
    sqft_textfield.text = sqft[0];
    price_textfield.text = price[0];
    avail_textfield.text = avail[0];
}

and then the same with the other buttons, for instance for 1B, just change 0 to 1
