[Greg Ronald]

Hi - totally ignorant on javascript need some help, getting the above error, my code is;

if('{!Event.Audit_Id__c}' == '')
{ 
window.location.href = 'https://eu1.salesforce.com/setup/ui/recordtypeselect.jsp?ent=01I20000000EQ62&retURL=%2Fa0F%2Fo&save_new_url=%2Fa0F%2Fe%3FretURL%3D%252Fa0F%252Fo&00N20000001ebQ6={!Event.Subject}&00N20000001ebQE={!Event.Id}'; 
} 
else 
{ 
alert('Event already linked to an Audit record'); 
}
