Stucking on redirecting to next question

Can you add some more information on how your data is stored, interface and process model is structured?

Hi balamanchari murugadas ,

could you elaborate more to better understand.

As per my understanding when you click on next button the process is ending instead of next question on the screen, i suspect you have used 'submit:true()' parameter in the next button. so the process is ending. Make sure 'submit:false' if you are using userinput task in the process.

)    --------- this is my code in this last save into in this part 

a!save(
ri!report_data.CanidateName,
loggedInUser()
),
a!save(
ri!report_data.score,
ri!score
)

I have to store score and name for this I need to use process model in process model 1 st question only coming next the node is ending I can't  able to create a processmodel. 

i didn't use process model but i want to use it.in interface next question redirecting is happening but not in processmodel node it is not opening it is ending in 1 question itself.

        }

    }

Remove the submit true value and pass it as true only when it is on the last question.

Add the same condition on submit, like you have on confirmation message

submit: local!currentIndex = local!totalQuestions,   like this right 

Yes. And to be sure it always works, make sure to wrap them in toInteger()
