Unused Local Variable error in Crowdsale contract #2610

Closed ErvinSenaj closed 7 years ago

ErvinSenaj commented 7 years ago

Hi everyone, I've been trying to create a crowd sale contract but it does not compile and comes with the error "unused local variable". Really not sure what to do as the code came directly from the ethereum crowd sale guide. image

This is actually a warning, just your IDE presents it as an error.

Remove the parameter names from transfer: contract token { function transfer(address, uint) {} }
