Add record using QR code with API_AddRecord function

Hi Comunity, I created a Rich Text field that I succeed in adding a record using QR code  with API_AddRecord call 

the challenge that I have is when I scanned it, save the new record but is not redirect to (var text redirect=URLRoot()&"db/"&Dbid()&"?a=q&qid=6";) and does  not link all fid list it on. see below my Rich text field

var text redirect=URLRoot()&"db/"&Dbid()&"?a=q&qid=6";
var text ADD = URLRoot() &"db/"& [_DBID_SCANS] &"?a=API_AddRecord"&
"&_fid_6="&[Student ID] &
"&_fid_9="&URLEncode("In-Person")&
"&_fid_22="&URLEncode((ToTimeOfDay(Now())));

"<img src=\"http://chart.apis.google.com/chart?chs=100x100&cht=qr&chld=|0&chl="&$ADD&
"&NextURL=" & URLEncode($Redirect)& "\"\"/>"


I have the same button but with url field type and it works perfectly 

I tried to find a code page but I did not succeed, I will appreciate any help.
