Or use "The Search" button ( he is very friendly sometimes ) .That button solved the problem for me. I mean i never asked how to add new units .. All i did was to corrupt my RA2/Yr several times and i still have questions wich i will never ask .
In 90% of cases i try it and the if i realy can't get it to work ( after like 2 moths ) then i ask it.. But most of the time i find what i'm looking for or i find out that it's hardcoded ( i wonder why
)...
So it's not that hard after you get used to it .!
