I am trying to replicate some code from a video, however, when I go to run the app and press the "Run the Experiment" button an error message says the following: 
Here is the code:
are there any red errors in your blocks?
what is the value of LabelN.Text?
make sure it is a number and not empty...

LabelN is not a numerical value it is set as N:, could that be the problem? Also there are no red errors at the bottom unfortunately.
yes of course
you only can calculate with numbers
