You have to define both the actions and the range here. Defining the actions is easy - there is a full tutorial on it:

The range is subjective. You have to go to the flop/turn range screens and pick the items that you think are "weak".
You should also go to pre flop->actions and pick "player had to show down" unless you're factoring in implicits which are covered in the getting started article:

Finally, on the general screen, you need to pick "...opportunities by range" which generates:
1/1 if a player flop cbets weak
0/1 if a player flop cbets strong (not weak)
0/0 if a player doesn't cbet
