Well Im takin it in to get the screw that keeps comin up fixed tomorrow, its possible right?

But i was screwin around with the other strings and not sure what its supposed to be set at.. any help? also is it easy to fix? or expensive.
Eh... you probably screwed up your action, but it won't be pricey to fix. Maybe $5-$10 from a guitar tech.
