wait for user input in for loop

[Roger111]

I'm pretty new to labview and I'm having a hard time figuring out how to do this. Basically, I need the user to press a GO button and data aquisition will take place saving it in an array, then the program will wait for the user to press the GO button again and the data aqusition will add more values to the array, and the whole process will repeat 5 times and finally it will average the values.

To try and figure out how to do this, I tried making a program that loops 5 times and adds a random number to an array with each loop (using shift registers) but I CANNOT figure out how to make each loop iteration wait on the user to press a button. Any advice?

Hi Roger,
you can use a dialog in your for loop, or better you use an event structure to react on user inputs. If you use the event structure you can count the button press events and store them in a shift register. With a compare function you can check if your limit is reached and react on it.
