Hi, For changing the contents of any gloabal variable, you have to access that global variable in a normal vi. Open a new vi, go to Block diagram -> Function Pallete->Structure-> Global variable. Then right click on this global variable-> replace by your global variable vi or create a new global variable vi. By doing this, u can access the value and can change it.
Hope it helps. Your feedbacks are welcome. Best Regards, Nirmal Sharma
