Hello i have some questions about map making.

First off,i'm new with ScmDraft because i have just used the normal StarEdit before. So my question is: Where is the trigger menu?!(In ScmDraft)

Next question: In my map i want you to get 1 mineral every 13 seconds and one gas every 7 seconds. Now i get this problem: I get 1 gas and 1 mineral EVERY second after 7 or 13 game seconds. I want to do so that you get 1 mineral every 13 second and 1 gas every 7 second and not every second.
The triggers are this(I take gas as example)
CONDITIONS:
-Elapsed time is at least 7 seconds
ACTION:
-Modify resources for Player 3: Add 1 gas
-Preserve trigger
What am i doing wrong?
