Where exactly did you use the event structure mentioned by Bob?
It isn't visible in your image!
What's the point of using a while loop that iterates only once???
suggestion: use a type-defined enum instead of a combobox to select a predefined number of cases!
Why don't you write you want to implement a Darts counter algorithm!?

I love how solving this small project became primarily understanding what the project is haha. The 501 and 301 reminded me of something as well that I couldn't point out, well done.
@Soccerfan a couple of things:
- Not everyone has the latest version of labview and will therefore not be able to open code from a more recent version. If you want people to help you debug something it is important to downgrade your code by "Saving for previous version" you VI:
- As GerdW said, if you want to subtract multiple times a different number (and most likely check when you hit 0 or go back to the previous number if it is actually a Dart Game) you should definitely spend a bit more time understanding Event cases and I would also add State Machines. You'll see it's a lot of fun, almost more than playing darts.

I think he was referring to my snippet that used an event structure.
@soccerfan,
Learn to use the Event Structure. It is one of the most useful features when dealing with a GUI. Just play around with it. This might be one place to start: Event-Driven Programming in LabVIEW

Thanks for your answer. You almost got it. I cosidere myself an intermadiate labview learner, i still have a long way to go. However ii know a fiew hings about events stucture and that is what i used in this problem
Your figure shows a While Loop around a Case Structure. An "Event Loop" is a While Loop around an "Event Structure". On the LabVIEW Structure Palette, the Case Structure is the fourth item in the Structure Palette, with the Event Structure being the fifth shown. Please learn about it, as it seems to be the "missing piece" in your understanding of the problem you are trying to solve.
Here is a simple example of an Event Loop. You can ignore the Invoke Node on the left -- that's just there to reset all the variables on the Front Panel to their defaut values before the code runs. Code this up or drag the Image to an empty Block Diagram (it's a LabVIEW Snippet, so it might magically become LabVIEW code). See how it behaves when you run it (including understanding when and how you stop the program). When you think you understand what is going on, try modifying the program by dragging the Number control outside the While Loop (so it is just "hanging out in the breeze" -- before you run it in this configuration, what do you think will happen? Did it behave as you expected? Why (or why not)?

Check my project that i posted earlier ( darts.app .vi) to have a grasp of what i am looking for.
Unfortunately you failed again in providing a downconverted version of your VI.
Somehow you aren't able to read our messages or willing to follow them…
