Sorry for the slow response. Let's start over and see if you can find where the problem is.

Disconnect the shift cable from the front derailler. Can you move the derailler by hand and shift the chain to the largest chainring? If so, not problems there. If not, did you mess with the limit screws at all?

Hold some tension on the disconnected shift cable (pull with your other hand) and try shifting with left shifter. Does it move through all of the appropriate clicks or not? If not, you might have somehow damaged the shifter or maybe something got in there and jammed things up. Try flushing with WD-40 and see if that restores proper function.

Once you've confirmed those two things the rest (barring any limit screw adjustments) is reattaching the cable and adjusting tension using the barrel adjuster (I'm assuming you have one on your bike, right?) until the bike shifts properly. I usually need a turn or two in addition to the tension I can add by hand when installing the cable.
