OK, I'm using Retail and I'm in Part 2 of the NTF Attack, and I'm making the event "Sleipner 1 done" where the first transport unloads the marines, undocks, and adds 1 dock to the DockCount variable. I'm up to the part where I add "modify-variable". When I add that op, instead of just the one line with the variable, and then being able to add a "+", as shown in the walkthrough, I get a 2 argument op, and am not able to add the "+". I think this is just something that was changed in FRED2 between the writting of the walkthrough and release, and I think I just put "1" in the second argument, but I would like to make sure. Here's a bad quality pic of what I get.

EDIT: I went ahead and put the "1" there, but now when I'm doing the "going in" events for Sleipner 2, 3, and 4, what do I put for the "is-event-true-delay"? Thanks.
