How can use form field in other user Task

hi all,i want to use defined variable form field user task into script task.but i took error

Take a closer look at the docs. If you’re using javascript, in your small example, I would expect your script task to look something more like

var system = java.lang.System;

var lv_temp = execution.getVariable('Users');
