problem with ajax form update

[akaballa123]

Hi There, Im a noob with ajax but really like the conept behind it. Iwanted to implement it into my form submit process. Basically, I want to create a security id each time the form is opened. When the user clicks submit, the for runs a javascript validation to check the form fields. If evrtything is fine, the ajax kicks in and sends the security id to mysql db through calling another php file. And then the for values are submit. However, my problem is that after implementing the code and logic, the form keeps showing an:

Object does not support method or property method on line 192

error. Eventhough this line has nothing to do with the ajax code in the file, I know it has someting to do with my ajax implementation.

please help!

ajax implementation and checkform:

function secIns()
{
 
 <!-- 
//Browser Support Code

	var ajaxRequest;  // The variable that makes Ajax possible!
	var err = 0;
	
	try{
		// Opera 8.0+, Firefox, Safari
		ajaxRequest = new XMLHttpRequest();
	} catch (e){
		// Internet Explorer Browsers
		try{
			ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
		} catch (e) {
			try{
				ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
			} catch (e){
				// Something went wrong
				alert("Your browser is not compatible!");
				return false;
				err = 1;
			
			}
		}
	}
	if(err == 0)
	{
	// Create a function that will receive data sent from the server
	    ajaxRequest.onreadystatechange = function(){
		if(ajaxRequest.readyState == 4){
			document.sessionForm.submitted.value = ajaxRequest.responseText;
		}
	    }
     //	ajaxRequest.open("GET", "serverTime.php", true);
     //	ajaxRequest.send(null); 


        //-->
  

	    var secID = document.getElementById('secID').value;
     	var queryString = "?secID=" + secID;
	    ajaxRequest.open("GET", "securityIDupdate.php" + queryString, true);
	    ajaxRequest.send(null);
	
	    return true;
	}
}

    }
    if( checkString(cTrainingDuration.value) == false )

        return false;
    }
    if (checkSubmit(cSubmit.value) == false)
    {
        alert('Form is already processed');
        return false;
    }
    elseif(secIns() == true)
    {

      cempName.value    = cempName.value;
      cID.value   = cID.value;
      cStartD.value   = cStartD.value;
      cEndD.value   = cEndD.value;
      cTrainingDuration.value = cTrainingDuration.value;
      return true;
    }
}

this is my submit form button:

<input class="button" type="submit" value="Submit" onclick="return checkForm(); " />

any help would be wonderful!!

it seems to clash with the javascript somewhere
