Im not sure where I would put the code so that if the usr does not have the amount of money needed it does not sell the item. Please help me, Ill post my buy verb.

Buy()
                set src in oview(2)
                var/item = input("What would you like to buy?") in list ("Desert Armor- 20 Gold","Nevermind")         
                switch(item)                    
                    if("Desert Armor- 20 Gold")
                        new /obj/Desert_Armor(usr)
                        usr << "You are handed a fine piece of armor."
                        usr.gold -= 20
                    else
                        usr << "You do not have enough gold!"
                if("Nevermind")
                    return

have it check in an if statement ho much gold they have. like
if(usr.gold <20)
usr<<"go away you bum"
something like that.

Put it after the if("Desert Armor") part.

if("Desert Armor")
if(usr.gold >= 20)
//continnue selling
else src << "You do not have enough gold."

Here, I rebuilt it to use a simple HasGold() proc that'll check if src has enough gold to pay the number (defined in the ()'s of the proc). If not, return the "You do not have enough gold!" error and end the verb. Otherwise, keep going.

Buy()
   set src in oview(2)
   var/item = input("What would you like to buy?") in list ("Desert Armor- 20 Gold","Nevermind")
   switch(item)
      if("Desert Armor- 20 Gold")
         if(!HasGold(20))
            usr << "You do not have enough gold!"
            return
         new /obj/Desert_Armor(usr)
         usr << "You are handed a fine piece of armor."
         usr.gold -= 20

      if("Nevermind") return

proc/HasGold(num)
   if(src.gold >= num) return 1
   else return 0

Do I have to define num?

Did you copy the code strait from my post?

In response to Foomer
No I typed it.

Buy()
set src in oview(2)
var/item = input("What would you like to buy?") in list ("Desert Armor- 20 Gold","Nevermind")
switch(item)
if("Desert Armor- 20 Gold")
if(!HasGold(20))
new /obj/Desert_Armor(usr)
usr << "You are handed a fine piece of armor."
usr.gold -= 20
else
usr << "You do not have enough gold!"

if("Nevermind") return
proc/HasGold(num)
if(src.gold >= num) return 1
else return 0

I can copy the whole thing to DreamMaker and it works fine for me (assuming I have the appropriate items included), so I don't know why you'd be getting an error.

I think I found a problem. You put it so that if usr had that much gold it told them that they didn't have enough. Or maybe im looking at it wrong.

if(!HasGold(20))
            usr << "You do not have enough gold!"
            return

This is my exact code for buy. The problem is when I try to buy the item and dont have enough gold it still lets me buy it an places my gold to a negitive number.

Buy()
                set src in oview(2)
                var/item = input("What would you like to buy?") in list ("Desert Armor- 20 Gold","Nevermind")         
                switch(item)                    
                    if("Desert Armor- 20 Gold")
                        if(!HasGold(20))
                            new /obj/Desert_Armor(usr)
                            usr << "You are handed a fine piece of armor."
                            usr.gold -= 20
                    else                            
                        usr << "You do not have enough gold!"
                        return
         

                if("Nevermind") return

Oh, if that's the case, you're using HasGold() backwards. Change it to if(HasGold(20)), and get rid of the !, because that's the same as asking "if src does NOT have 20 gold"

Modified code:
<HE>
Buy()
set src in oview(2)
var/item = input("What would you like to buy?") in list ("Desert Armor- 20 Gold","Nevermind")
switch(item)
if("Desert Armor- 20 Gold" && usr.gold > 19)
new /obj/Desert_Armor(usr)
usr << "You are handed a fine piece of armor."
usr.gold -= 20
else
usr << "You do not have enough gold!"
if("Nevermind")
