7 segement LED display using esp8266 lolin wemos

I'm trying to follow this guide: GitHub - leoclee/7-segment-clock
When I get to step 7 I don't get the option "sketch data upload". I've followed everything exactly as it says. I'm also getting an error in my code but want to address step 7 first.

You can't upload code that won't compile, so your priorities are wrong.
