Now let's say the pot has $100 in it and your opponent bets $20, you have to call $20 to win $120 or 6:1 (120:20) on your money. So its a call.
If your opponent bets $50, then you have to call $50 to win $150 or 3:1, so now you are not getting the right "price" to call.


That's a pretty good explanation, but to take it a bit futher for mathchallenged people llike me :
=== 6:1 (pot odds) vs 4:1 (drawing odds) === ("Correct" price) :
4:1 to make the flush, so for every 5 times you play for that flush draw, you'll hit it once (on average).
So, assuming a $120 pot and a $20 call for each game, you'll spend $100 to win $600.
You'll win 1 /5 so :
bets : 5 x $20 = $100
lose : 4 x $20 = $80
Win : 1 x $120 = $120
$120 (won)  $80 (lost) = $40 profit
=== 3:1 (pot odds) vs 4:1 (drawing odds) === ("InCorrect" price) :
You still win 1 /5 (4:1 drawing odds).
bets : 5 x $50 = $250
lose : 4 x $50 = $200
Win : 1 x $150 = $150
$150 (won)  $200 (lost) = $50 net loss
All that said, I just read in another thread where a player mentioned that
pot odds / drawing odds is more valid in fixed limit games, than in nolimit or pot limit games.
