Formula help

I am attempting to create a new record in another table and prefill the parent table.  It works on existing records.  For example I created a test record and when I click my button (formula shown below) then it creates the parent record as it is supposed to.  When I click new record on the child and go through the steps, click on the button, it says the record does not exist.  


Formula:
URLRoot() & "db/" & [_DBID_TABLE_1] & "?a=API_AddRecord&_fid_345=" & URLEncode ([Record ID#])& 

"&_fid_365=" & URLEncode ([BU-Plant])& 
"&_fid_347=" & URLEncode ([Related Point of Origin])& 
"&_fid_350=" & URLEncode ([Related Point of Discovery])&

"&_fid_291=" & URLEncode ([Disposition Comments])& 
"&_fid_356=" & URLEncode ([Related Part Location Name])&

"&z=" & Rurl()& "&rdr=" & URLEncode(URLRoot() & "db/" & Dbid() & "?a=dr&rid=" & [Record ID#])
