dundeebarefeet, don't mess with anything inside the shifter; no messing with that screw will not help the problem. What you first need to do is get everything back to where it was before; meaning disconnect front derailleur cable at the derailleur (not the shifter!) and re-position the front derailleur where it was before. The reason the cables look different in the shifters is the front derailleur cable is too loose. the shifter has a black tab about where your thumb will lay with your right hand on top of the brake/ shifter. Pull on the derailleur end of the cable while you repeatedly push down on the tab. Once the tab stops clicking, pull the cable end at the derailleur end tight and attach it to the derailleur; make sure the housings are also in place. If you try and shift the front derailleur now and it doesn't move on the first click, then the cable is not yet tight enough. You can either disconnect the cable and pull it tighter or turn the inline adjuster; to tighten the cable turn the adjuster counter clockwise as if you were unscrewing it. If the adjuster comes apart, it means you need to disconnect the cable from the derailleur again, screw the adjuster as far as it will go together and then reattach to the derailleur.
