    Problem with javascript

    Hello guys,
    My script is used to check some text field before the user upload some text, below you can see the code:

    Code:
    // JavaScript Document
    function Check()
    {
    	var no_error=true;
    	var pattern=/^[A-Za-zΑ-ΩΆΈΉΊΌΎΏα-ωάέήίόύώ!%()-:,.;(\s)]$/;   //oi xaraktires p dikaioute na eisagei o xristis--> http://www.evolt.org/node/36435
    	
    	txt_quote=document.getElementById('add_quote').value;
    	if(txt_quote.length>0 && txt_quote.length<2000)
    	{
    		for(var i=0;i<txt_quote.length;i++)
    		{
    			if(!txt_quote.charAt(i).match(pattern))
    			{
    				document.getElementById('add_quote').style.backgroundColor='#FF3333';
    				no_error=false;
    			}
    			else
    			{
    				document.getElementById('add_quote').style.backgroundColor='white';
    			}
    		}
    	}
    	else
    	{
    		//is bigger than 2000 characters or is null
    		document.getElementById('add_quote').style.backgroundColor='#FF3333';
    		no_error=false;
    	}
    	
    	txt_quote=document.getElementById('add_name').value;
    	pattern=/^[A-Za-zΑ-ΩΆΈΉΊΌΎΏα-ωάέήίόύώ!%()-:,.;]$/;  //No space
    	if(txt_quote.length>0)
    	{
    		for(var i=0;i<txt_quote.length;i++)
    		{
    			if(!txt_quote.charAt(i).match(pattern))
    			{
    				document.getElementById('add_name').style.backgroundColor='#FF3333';
    				no_error=false;
    			}
    			else
    			{
    				document.getElementById('add_name').style.backgroundColor='white';	
    			}
    		}
    	}
    	else
    	{
    		document.getElementById('add_name').style.backgroundColor='#FF3333';
    		no_error=false;
    	}
    	
    	txt_quote=document.getElementById('add_links').value;
    	pattern=/(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/;  //
    	
    	if(txt_quote.length>0)
    	{
    		if(!pattern.test(txt_quote))
    		{
    			document.getElementById('add_links').style.backgroundColor='#FF3333';
    			no_error=false;
    		}
    		else
    		{
    			document.getElementById('add_links').style.backgroundColor='white';
    		}
    	}
    	else
    	{
    		document.getElementById('add_links').style.backgroundColor='white';
    	}
    	
    	return no_error;
    }
    
    function countChars()
    {
    	var text=document.getElementById('add_quote').value;
    	document.getElementById('count_characters').innerHTML=text.length.toString() + " από 2000";
    	if(text.length>2000)
    	{
    		document.getElementById('add_quote').style.backgroundColor='#FF3333';
    	}
    	else
    	{
    		document.getElementById('add_quote').style.backgroundColor='white';
    	}
    }
    function restore_color(id)
    {
    	document.getElementById(id).style.backgroundColor='white';
    }
    function restore_color_to_all()
    {
    	document.getElementById('add_quote').style.backgroundColor='white';
    	document.getElementById('add_name').style.backgroundColor='white';
    	document.getElementById('add_links').style.backgroundColor='white';
    	document.getElementById('add_quote').focus();
    }
    After that i call the check() function like this

    Code:
    ...onsubmit="return Check()">
    This script works just fine with internet explorer but it doesnt work with chrome or firefox. Any ideas?

    (i guess something is wrong since internet explorer works and chrome/firefox not )
    I also forgot to mention that the script works just fine when i am testing the webpage on my pc, the problem is when i used the webpage not locally but over the net, is there any setting should i change on my hosting server?
