Something is amiss in the outpost....

[Styxamix]

I guess I am just a little slow on the uptake. When I input values (abab) into the genetic code slot do I press the enter key or click on the difficulty button, does it automatically do it itself? So far, for me pressing the enter key does nothing, clicking on a difficulty button clears the input value. So the real question I need answered is what am I supposed to be doing? Also am I just putting in random values or do I find them in a particular spot?

Thanks for any help.
