Busted vendor script not giving item, help please.

So this is a modded EzVendor script that I have made to email me about purchases much like the Vendopf Vendor I like to use. I got it to email me, but it is not giving me the inventory. Any help would be greatly apreciated. Thank you.

integer price = 5; //Price of the object goes here, change to whatever you want
string item = "foobox"; // Write the EXACT name of the object you want to sell
string wrong = "Sorry, that is not the correct price"; // This is the message your vendor will say when the person underpays the vendor
string over = "You have overpaid, here is your change"; //This is the message your vendor will say when a person overpays the vendor
string thank = "Thank you and enjoy your purchase"; //This is a message thanking your buyer for purchasing your object.
string address = "name@domain.com";//email address
string subject = "vendor sale";
string message = "you have sold";
default
{
    on_rez(integer total_number)
    {
        llResetScript();
    }
    state_entry()
    {
        llWhisper(0, "Vendor systems go");
        llRequestPermissions(llGetOwner(), PERMISSION_DEBIT); //Make sure you click YES when the debit dialog pops up or youll have some very unhappy customers >_<. # This insures that they will get their change back if they overpay or underpay
    }
    money(key id, integer amount)
    {
        if(amount < price)
        {
            llSay(0, wrong);
            llGiveMoney(id, amount);
        }
        if(amount > price)
        {
            llSay(0, over);
            llGiveMoney(id, amount - price);
            llGiveInventory(llDetectedKey(0), item);
            llEmail((string) address, (string) subject, (string) message + (string) item + " to " + llKey2Name(id));
        }
        if(amount = price)
        {
            llSay(0, thank);
            llGiveInventory(llDetectedKey(0), item);
            llEmail((string) address, (string) subject, (string) message + (string) item + " to " + llKey2Name(id));
        }
    }
}

Looks like this is your trouble:

if(amount = price)

Change that to if(amount == price)

= is used for assigning values to variables (x = 1), whereas == is used to compare two different values (if x == 1)

Also, as a side note, instead of using 3 if statements in the money() event, it would probably be better to use else if's for the 2nd and 3rd.

Hope this helps.
