I'm new to the website-building thing and I can't find the solution:

I made a script with dreamweaver.

After the form-validation, I have an alert if the field doesn't has a valid number.

After the alert opens an empty window.

I want, after that alert no window. Only if the validation is right.

What am I doing wrong?

I'm sorry for my English. I hope you understand me.

This is the script:

<script type="text/javascript">
function MM_validateForm() { //v4.0
if (document.getElementById){
var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
for (i=0; i<(args.length-2); i+=3) { test=args[i+2]; val=document.getElementById(args[i]);
if (val) { nm=val.name; if ((val=val.value)!="") {
if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
if (p<1 p==(val.length-1)) errors+='- '+nm+' must contain an e-mail address.\n';
} else if (test!='R') { num = parseFloat(val);
if (isNaN(val)) errors+='- '+nm+' must contain a number.\n';
if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
min=test.substring(8,p); max=test.substring(p+1);
if (num<min max<num) errors+='- '+nm+' must contain a number between '+min+' and '+max+'.\n';
} } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is required.\n'; }
} if (errors) alert('The following error(s) occurred:\n'+errors);
document.MM_returnValue = (errors == '');
} }
function MM_openBrWindow(theURL,winName,features) { //v2.0


<form action="form1post.php" method="post" onSubmit="MM_validateForm('quantity','','RisNum'); MM_openBrWindow('about:blank','formtarget','width=300,height=300');return document.MM_returnValue" target="formtarget">
<select name="item">
Quantity: <input name="quantity" type="text" id="quantity" />
<input type="submit" />
