textbox and dropdown communication

Hello all,

Is there a way I can programaticly select a value in a drop down box, depending on what is in another textbox

in IE6.0 i did it by doing

function ModifyIt (frm1) // drop down name is aaa
{

var temp;
temp = frm1.textBox.value;
if (temp.charAt(0) == "A")
{
frm1.aaa.options.value = frm1.aaa.options[1].value;
}
//rest of code;

i trigger the event with a onKeyup = " ModifyIt(this.form)"

this coding works in ie6 but not in nn4.7
can anyonme help me.
i tried all sorts of things but to no avail


regards
