Discussions > Error while uploading Firefly_Firmata

When uploading the Firefly_Firmata I get an error message saying the following:

\\fadwincocifs002\homedata$\harlentyle\My Documents\Arduino\Firefly_Firmata\Firefly_Firmata.ino:505:19: warning: multi-character character constant [-Wmultichar]

if ((str[0] > '50') || (str[0] < '0'))

But the sketch also uploads to the board, saying Done uploading. I'm using Arduino IDE 1.6.6
Is this a problem, and will this affect the operation of firefly?

Any help will be much appreciated, thank you
