i just decided to pick it up today and already run into errors, my future bodes well.

i cant figure out why this :

for (var i=0;i<=tempstring.length-1;i++) {

	alert(tempstring.charcodeat(i));

and this :

for (var i=0;i<=tempstring.length-1;i++) {

	alert(tempstring.charat(i)) ;

dont alert, but this does :

for (var i=0;i<=tempstring.length-1;i++) {

	alert('Character = ' + tempstring ) ;

any help?
