user67788: Could someone point out what exactly I'm screwing up here and provide a specific solution. Here's the error message:

This report would have more information with

option enabled in File -> Preferences.

And here's the code:

Like I said-what's going on? Thanks!

user67819: use { pinMode(led, OUTPUT); } to create a new scope and if you don't need new scope just remove (, )
