Magic Buttons - New Method?

A while back I used Magic Buttons to check/uncheck a checkbox. This URL Formula still works on the old app but with an "Unsupported Content" alert. Using this same method does not work on a newer app I've created. 

I've read that a new method is to move the code to a Code Page then link the URL Formula to that code page for execution. I have been unable to get this to work.

Does anyone have a documented, current method for a working report button to check/uncheck a box (the refresh the report)? 

~~~~Previously Used  (deprecated) URL Formula~~~~

var text URL =

If([Validated] = false,

URLRoot() & "db/" & Dbid() & "?a=api_Editrecord&rid=" & [Record ID#] & "&_fid_52=1&_fid_115=" & URLEncode(User()),

URLRoot() & "db/" & Dbid() & "?a=API_EditRecord&rid=" & [Record ID#] & "&_fid_52=0&_fid_115=" & URLEncode(User())
);

"javascript:" &
"$.get('" &
$URL &
"',function(){" &
"location.reload(true);" &
"});"
& "void(0);"
