Can you click on a field within an email to update a quickbase form?

This formula tested OK.  LMK if you need help with adjusting the color or the size of the button.

var text URL = URLRoot() & "db/" & Dbid() & "?act=API_EditRecord&rid=" & [Record ID#]
& "&_fid_355=1" // replace the 355 with the field ID of your checkbox field  
& "&disprec=1"  // this will land the user on the record after they click.
& "&apptoken=xxxxxxxxx"; 
// in advanced settings for the app, you may have the need for application tokens enabled
// I suggest that you disable this need, but if you do want to use application tokens 
//an extra layer of security, you will need to create an applicaiton token and supply it 
// here.
