It worked fine for me on IE 5.5, I just tested it with the following code:
<script>
var ch = 8;
if ((ch >= "a" && ch <= "z") || (ch >= "A" && ch <= "Z" ) || (ch >= "0" &&
ch <= "9" )) {
alert('good');
}
</script>
What web browser are you running this on? Try using single quotes instead of
double quotes. You could also use a regular expression to do this.

Subject: Javascript grammer help?
The following sentence works fine in Javascript
if ((ch >= "a" && ch <= "z") || (ch >= "A" && ch <= "Z" ) )
but if I change to :
if ((ch >= "a" && ch <= "z") || (ch >= "A" && ch <= "Z" ) || (ch >= "0" &&
ch <= "9" ))
The (ch >= "0" && ch <= "9" ) part won't functioning.
