Hello

Can someone please tell me where i am going wrong with this code? The saveURL is simly not being executed, and the record stays on the newly created record after save. If you cancel, yes, it does revert back to the parent, but the save ALWAYS stays on the child, where i would like it to go back to the parent (ticket is the parent, ticket comment is the child)

/apex/AddComment?CF00N90000002Fdf1={!miiHelpDeskT2__Ticket__c.Name}&CF00N90000002Fdf1_lkid={!miiHelpDeskT2__Ticket__c.Id}&CF00N90000002Fdf8{!miiHelpDeskT2__Ticket__c.miiHelpDeskT2__Ticket_Manager_Name__c}&CF00N90000002Fdf8_lkid={!miiHelpDeskT2__Ticket__c.miiHelpDeskT2__Ticket_Manager_NameId__c}&CF00N90000002zw4A_lkid={!miiHelpDeskT2__Ticket__c.miiHelpDeskT2__Subject__c}&CF00N90000002zw4F_lkid={!miiHelpDeskT2__Ticket__c.miiHelpDeskT2__Description__c}&sfdc.override=1&retURL=%2F{!miiHelpDeskT2__Ticket__c.Id}&saveURL=%2F{!miiHelpDeskT2__Ticket__c.Id}

Its worth mentioning that without the below part, the whole custom button does not work

&sfdc.override=1

I am getting this error when I am trying to download and install Force.com IDE for Vista 32 bit.
