I'm trying to run a go program using LiteIDE x22 but I get the message

I think this means it's looking for it on my harddrive instead of online right? (btw I'm pretty clueless about programming just trying to something some else wrote) how to I get it to access the web? here's the full code

oh also would it be possible to modify it to output as .txt or .mobi? if not I'll just convert using Calibre. Thanks in advance. Oh if it matters I'm using windows 7 64-bit
