Spelling/Grammar - Where's the error?

[gfx08]

No catch with this, I just genuinely can't find the error? Chances is are it's me not being very clever lol.

In the 1870's Alexander Grahan Bel a Canadian scientist, inventor, engineer and innovator created the first practical telephone.

Thanks for replys in advance x

You spelled 'Graham' as 'Grahan' and you missed an 'l' in 'Bell'

Stop trying to bypass the "intelligence tests" for one of those botting communities. If you can't figure this out you need to stop trying to bot.

HINTS:
1. Proper nouns
2. Commas
