User task Not working

Hi all,
I have created a simple process in camunda modeler with demo user in which, user fill the form and than it goes to another user for approval say John but in my case after creating instance user fill the form but not able to execute next process .please help me out , help will be appreciated.

Here, I am attaching a few pictures that can help in understanding the Problem.

@nileshjha0007 In the modeller the value specified in Script Format is absolutely wrong. The values should be either “javascript” or “groovy” .

Don’t use this Name==“Nilesh” hence its not a valid value for script format.
