Trig help please :))

Ok heres a quick, single, (prob. n00bish) question.

I want this action entered into the world editor to basically subtract 1 from the "Lives" variable. Basically after all 5 lives are gone the player will get a message and a Defeat screen.

Heres the code as I would like to have it:

Set Lives[(Player number of (Owner of (Dying unit)))] = Lives[(Player number of (Owner of (Dying unit)))] -1

But for some reason the editor wont let me add in the -1 at the end. Any idea why not? Oh yes, the Lives variable is just an integer vari. with array.

Thanks alot guys.

-Huh

In the set variable area, choose Arithmatic.

Then set the Lives[(Player number of (Owner of (Dying unit)))] as the first part of the arithmatic, and the - 1 as the second part.

So its:

1. Choose set variable as action
2. Put Lives[(Player number of (Owner of (Dying unit)))] as the variable
3. Choose "Arithmatic" as the set to area
4. 1 + 1 will apear, change the first 1 to Lives[(Player number of (Owner of (Dying unit)))]
5. Change the + to -
6. Hit ok to everything and your set.
