Aren't you forgetting something here? Your argument is sound if it is valid and your premises are true. Interesting that you left off that last part.
Yes, it was irrelevant to the point so I simplified it into being "logically valid"..perhaps its incorrect terminology but an argument is considered valid if it has a logical structure, but is that the same as saying it is logically valid? I would think an argument could only be logically valid if its premesis are true.
