Commas missing from where they’re needed, and commas thrown in where they don’t belong… Yep, it looks like a typical day for Mercenary Proofreader. 🙂
The first bit contains a comma splice (a comma used where you need a period instead, or at least a semicolon) and a run-on (no punctuation at all). The second bit contains a run-on (comma missing before conjunction but), a comma splice (that should be a period, not a comma, after anyway), and a typo.
