 Take a look a the initial of the command:''[[:de:create:functions:gotopage]]''. It tells us that it will make you jump to the specific page directly without executing anything else on the page of origin. In this example, not even ''text()''. If you are aware of the cause, the solution is simple: Move ''text()'' in front of ''goTopage()''. Take a look a the initial of the command:''[[:de:create:functions:gotopage]]''.
