list_name = txt;
alert(list_name);
document.getElementById('list_name_c').value = list_name;
}



// ]]></script>

</p>

The form is able to send the values of First Name, Last Name, Email to SuiteCRM prospects table. But checkbox values are not being sent to prescribed field of β€˜list_name_c’. Nor the alert is being displayed.

However, the same code is able to save the checkbox values in CRM once the HTML syntex are added the code and code is saved as .html page. Alert is also displayed.

Can some able programmer or developer help me?
