        src << "Give Gold to who??"
        return
    var/give = input("Give how much?","Give") as num
    if(give <= 0)
        src << "Enter a amount that is vailed!"//Make sure no negitive gold.
        return
    if(give <= src.Gold)
        src.Gold -= give
        M.Gold += give
        M << "[src] gave you [give] Gold!"
        src << "You gave [M] [give] Gold!"
    else
        usr<<"You don't have that much Gold!"
        if(M.Gold<= 0)
            usr <<"[M] is broke."
            return

switch(i)
if("Buy Dilithium 12creds 1unit") // the program already knows what it's comparing (r). this was established with the line 'switch(r)'. now the program is checking to see what 'r' equals. just use if("example") to do so, because we've already checked to see what we're looking at
usr.wealth-=24
usr.dilithium+=1


if("Buy Tools 6creds 1unit") // the program already knows what it's comparing (r). this was established with the line 'switch(r)'. now the program is checking to see what 'r' equals. just use if("example") to do so, because we've already checked to see what we're looking at
usr.wealth-=6
usr.Tools+=1


if("Sell Dilithium 12creds 1unit")
usr.wealth+=6
