monitor wont print variable

Ok so when i run the program on a computer it works until i tell it "monitor.write(x)" it says that it is trying to index a nil value. However i have already asked the user to give it a value. Not sure how to fix this.

The variables "monitor" and "Monitor" are not the same thing.

thanks for spotting that, but i still get the error attempt to index a nill value

I'm still seeing miscapitalisations within the paste.
