Hi Jacktahoe,
what have you done so far? You can use a loop with an event structure. Use a parallel loop to run the counter. Use a case structure to switch between count up and down.

Hi Mike,
So far I have implemented a counter which can count both up and down and to do this I used case structure to switch between up and down. The only issue left unhandeled is that my counter doesnt let the user input the values in the countdown/up mode. If you can suggest me on how to do that. i tried using local variables to read the values from the window and rewiriting back, but everytime I do this it overwrites the new value (user input) with the old calculated values.
Thanks
