ActionScript 2.0 :: Click 2 Times On The Next Text Area To Move The Focus?

I initialized the variables, the TABBING thing doesn�t work and when I select something from the combo box, seams that the focus doesnt move to the next are even if I click on it, I need to click 2 times on the next text area to move the focus.HERE is the code that i am using...

var a_1 =""; //text areas inputvar a_2 =""; //text areas inputvar a_4 =""; //text areas inputvar a_6 =""; //text areas input var cb_slang:Object = new Object(); //combo boxm_s_lang.addEventListener("change", cb_slang);cb_slang.change = function(){ m_g_slang = m_s_lang.value;}var cb_stype:Object = new Object(); //combo boxm_s_type.addEventListener("change", cb_stype);cb_stype.change = function(){ m_g_stype = m_s_type.value;}
