Hi guys, first i hope u will understand me...
So i want to make a javascript to be shown if somebody chooses option A to show the javascripts for the A1,A2,A3 and if they choose B to show javascripts for the B1,B2,B3. So the A and B it will firstly asked as options from a <select> tag
<select name="AorB" >
<option value="" selected="selected">Select...</option>
<option value="A" >Option A</option>
<option value="B" >Option B</option>
I'm using this way of javascript (Error Alerts):

<SCRIPT language=JavaScript>
function check(form) {
if (form.Password.value == "")
{ alert("Please enter your Password."); form.Password.focus(); return;}
if (form.Password.value.length < 8)
{ alert("Please enter a valid Password."); form.Password.focus(); return;}
P.S: I don't want to make complications when they choose A to get B option javascripts or reverse.
