include fil med javascripts

jeg har et simpelt tekst animations script som gør at teksten fader mellem 3 linier. dog har jeg brug for at scriptet bliver på en side men skal includes i en anden side - hvordan gør man det?

scriptet:
<html>
<script>
mesk=new Array();mesk[10]=\"A\";mesk[11]=\"B\";mesk[12]=\"C\";mesk[13]=\"D\";mesk[14]=\"E\";mesk[15]=\"F\";A=10;B=11;C=12;D=13;E=14;F=15;let=\"ABCDEF\";function mes(num){if(let.indexOf(num) != -1){return eval(num)};else{if(num < 10){return eval(num)};else{return mesk[num]}}};
function color(begin,einde,stappen,stap){
hh1=(mes(begin.charAt(0))*16)+mes(begin.charAt(1));
hh2=(mes(begin.charAt(2))*16)+mes(begin.charAt(3));
hh3=(mes(begin.charAt(4))*16)+mes(begin.charAt(5));
pp1=(mes(einde.charAt(0))*16)+mes(einde.charAt(1));
pp2=(mes(einde.charAt(2))*16)+mes(einde.charAt(3));
pp3=(mes(einde.charAt(4))*16)+mes(einde.charAt(5));

if(hh1 < pp1){ff1=hh1+Math.floor((pp1-hh1)/stappen*stap);
ff1=eval(\"\\\'\"+mes(Math.floor(ff1/16))+\"\\\'\")+eval(\"\\\'\"+mes(ff1-(Math.floor(ff1/16)*16))+\"\\\'\");}
;else{ff1=hh1-Math.floor((hh1-pp1)/stappen*stap);
