Two part question here, hopefully they are both tiny.

Lets say I have something really simple like a text field and a select/option combobox.

I want to change the combobox to 'other' anytime the text in the textbox changes.


Code:
      	    <input size="10" type="text" id="itemtext">

            <select size="10" align="left" id="itemcombo" style="width:20em;">
              <option value="0">Other</option>
              <option value="1">abc</option>
              <option value="2">def</option>
              <option value="3">ghi</option>
            </select>
for the next part, I also want the combobox to update the text field with the VISIBLE selection, but keep the VALUE as being the number (mysql unique key)
I already made the combobox update the textfield with onchange="itemtext.value=this.value", but this changes the textbox to the value field. Is the visible text as easy to get at?

Thank you, and sorry for the newbie questions.
