copy the data from one field to another using click on button on same record it

Hi Preeti,

You should enclose your [Login User] field with the ToText() function and there is also a quotation missing after the 10= (it's erroneously after the User reference). You may also need to verify that the app does not require app tokens (or add the token to your formula).

URLRoot() & "db/" & Dbid() &
"?a=API_EditRecord" &
"&rid=" & URLEncode([Record ID#]) &
"&_fid_10=" & URLEncode(ToText([Loggin User])) &
"&rdr=" & URLEncode(URLRoot() & "db/" & Dbid() & "?a=td")​

I have not 'debugged' the rest of your code, but these omissions stood out to me as the likely issues provided all else is correct.

Let me know if this helps 😊👍
