geht roughly translates to works or functions in the same way that we use the verb go in english, like the heater is going..
es geht - it works
geht's los - start
der Fernseher geht nicht mehr an - the television doesn't work anymore
it all depends on the context i guess. you could use our exchange for example, you had a question the function of which is to provide you with knowledge, and i answered in a way that wasn't exactly relevant, so you could have said - darum geht das hier nicht, oder?
