Hi All,

Just wondering if you could give some help with some javascript code 
please.  I have some form validation code which simply sees if a field is
empty or not: 

if (document.particulars.username.value == "") { 
       alert('Please Enter a Username'); 
       return false; 
   } 

But what can I add to see if the username field contains the character ';'
or has any spaces.  If it does contain any of these, it must bring up an 
error. 

Help would be greatly appreciated.

Thank you.
