Are you talking about required inputs?

Yes thats it! Thanks!

Now to only be able to click the right input as they are all 2px on my screen :S. Is there a way to expand the vi connector?

It's generally preferred to group certain inputs as cluster so that connector terminals are not more than 16 as NI recommended.

This is why you should upload your code, not a picture of your code, when looking for debugging help. In the end it will save everyone a lot of time.
