Pues dado que no ASP sino de javascript, normalmente te recomendaría que fueras a dicho foro, pero como eres de los pocos que un código tan largo lo encierra entre [ CODE ], te diré, jejeje:

En el evento OnChange del Combo coloca esto:

document.forms[0].TuCaja.value = this.options[this.selectedIndex].text
