Want to display variables in sc_task form

[MayurChaudhari]

I want to display the tick marked variables in sc_task form under variable section how can i do that?

Is following script correct?

task.short_description = 'IT Work Request For :  '+current.variables.requested_for.getDisplayValue();

    task.please_provide_a_short_description = ' ' +current.variables.please_provide_a_short_description.getDisplayValue();

    task.assign_to_self = ' ' +current.variables.assign_to_self.getDisplayValue();

        task.assignment_group=current.variables.assignment_group;

task.due_date=current.variables.please_select_date;

@MayurChaudhari 

why are you setting the value to variable using task object?

why to use these 2 lines?

task.please_provide_a_short_description = ' ' +current.variables.please_provide_a_short_description.getDisplayValue();

task.assign_to_self = ' ' +current.variables.assign_to_self.getDisplayValue();
