Thank you very much for the quick replies, it's appreciated.
I just realized I might have another small problem and I'm unfortunately away from my machine with Construct temporarily. I'm assuming that I would have the sequence be: when enemy moves within x pixels of player, random number is rolled, compare random number to enemy private variable, if random number is (for example) 1, do kick, 2 do punch, etc. However, I want enemies to do one attack slightly more often than others, like: if random number is 1, kick, 2 or 3, punch, 4, 5, or 6, shoot. Could you tell me how I can set specific ranges for variables as in this example?
