jake6502 is correct - the result is a slice that needs to be indexed (you might use jsonvals[2].Int()).
I'd suggest that instead of using that gjson package, you might consider using the standard library's encoding/json package, which enables you to define a struct type that mimics the expected JSON; something like this: https://play.golang.org/p/uodaEwbjDZR This is nice because the json package takes care of a lot of validation before you need to look at the data.
