Switch, cases & returns. - Carlton - 17.06.2010

Hey, this codes' been bugging me for a bit now. Here's a little detail: My business system needs products for items to be bought, now, so the business i'm buying from has 0 products, OK, but i'm still able to buy the item, it says:

pawn Код:
command(buy, playerid, params[]) {
    new stringformat[128];
    for(new i = 0; i < TOTAL_BUSINESSES; i ++ ) {
      if(IsPlayerInRangeOfPoint(playerid, 55.0, BizData[i][bExPos][0],BizData[i][bExPos][1],BizData[i][bExPos][2])) {
        if(BizData[i][bProducts] < 1) return SendClientMessage(playerid, COLOR_SYSTEM, "[Error]: This store has no products.");
                  switch(BizData[i][bType]) {
                        case 0: {
                    // The rest of the code doesn't need to be shown, but you get the process, it goes to the cases even thought I returned the message and the products are 0
I tried using return 0 and ignoring the message and return 1, but the same effect.

I am not totally sure but if(BizData[i][bProducts] < 1) doesnt this mean the shop has products? and the next line is
return SendClientMessage(playerid, COLOR_SYSTEM, "[Error]: This store has no products.");

Im not very experienced but doesnt this mean even if there are items it still says the error?
try doing: if(BizData[i][bProducts] < 0) try this and check if this helps.

If this helps im very glad to help you, coz i learned something then too.

< 1 - is checking if the biz has 0 products or below,
< 0 - however is checking if the biz has -1 products or below

Incorrect, read your statement in words not in a coding language.

" If the Business Products is less than 0 ", why would I check if a business's products are not even 0, I never heard of something with a negative amount of products.
