how to pass a cdt through an interface

Certified Associate Developer
Happy Friday Appian Community ,
I cannot figure out how to pass data though an interface a second time.
I have tried to copy how it was done in the first write to data store.
maybe I am trying to save it in to many different places?
here is my submit buttons code: 
primaryButtons: {
      a!buttonWidget(
        label: "Approve",
        icon: "check",
        value: true(),
        saveInto: {
          a!save(ri!GFIM_User_Access_User_Information,ri!GFIM_User_Access_User_Information),
          a!save(ri!GFIM_User_Access_User_Information.supervisorsDecisionDate,now()),
          a!save(ri!GFIM_User_Access_User_Information.supervisorDecision,true)
          },
        submit: true,
        style: "PRIMARY"
      )
    },
here is my user form input
output
write to data store input
output:
anything you could advise would be helpful.
thanks,
Kevin
