error message

I'm new to the arduino program and I tried to do the project 2 and wheni type the code in it gives me this:

exit status 1 'output' was not declared in this scope

what should I do?

can you post the code you are working with?

what should I do?

Is the word used in a pinMode call? If so then it all needs to be in capitals. This language is case sensitive.

declaring 'output' with the correct scope would fix it. or capitalizing if it's in pinMode
