@pankaj

  1. First format your code (like I did)
  2. Specify which line number you are getting stuck. Few people have time to go through your entire dump

i have to required disply record in field(in .js file HERE → fieldtype: “Data”,label: __(“Que”),) from mysql database table but how?
and i have also required if next button is click and after show previous button (in .html) but how?
i am also fresher in this so, i don’t know how i execute my code.

how i execute select query and where in my code.
and how i hide the previous button and where i execute code in my file.

@pankaj Can’t really figure whats going on. Hope someone else on the forum can help you.
