"{CMDWHENISAY}" is a token that will be replaced with the contents of the "When I say" field of your command, I.E. the "name" of your command". This means you could copy these actions to any command and they wouldn't interfere with eachother.
You're looking to increment the value by 1, so you need to use the "Computed value" option of your "Set an Integer Value" action, set it to "Add", select "Compute against a value", set it to "1", and check "Evaluate Not Set as zero".
