Minimum no. of units

Hi Nigel,
      You can set a minimum number for particular products and a maximum number overall, but the code that checks the overall quantity has been exceeded is executed when products are added to the "cart".   To throw messages at that  point would probably become irritating to customers as, even when they know about the limit of 12  they would get the message until they reached the minimum of 12.

I think you will need to add code to the checkout process to check this to make this work OK.  It's an unusual requirement to have a minimum overall number of products I would have thought. Usually these things are achieved by having a minimum order value instead. Have you suggested this to your client as an alternative approach?

Ah, yes - I can see that's a perfect example of when it would be required :-). I suspect they would want to sell in multiples of either 6 or 12 with a minimum of twelve.

I'd be happy to help them test it :-) 
FYI - The code used for the maximum quantity appears in pc/instPrd.asp (& a couple of others) and is coded as follows :-
if countCartRows(pcCartArray, ppcCartIndex)=scQtyLimit then

Where scQtyLimit is the Maximum quantity value set via the  "Store Settings > Order & Customer  Related".

I think you should place your code where the related "Minimum Order Amount" rules are enforced. Note, there are separate limits for Wholesale and Retail cutomers.

For Wholsale customers there are more locations with associated code, but There are 5 files in the "pc" folder that contain the "scminpurchase" but the key one, I suspect, is checkout.asp, although I would check all of them if I were you. NOTE - The Wholesale minimum is referred to in a couple of other files as well.

In checkout.asp there is code at line 197 in the version I'm looking at (V3.11) :-

        if calculateCartTotal(pcCartArray, ppcCartIndex)<scMinPurchase then
        'Retail minimum not met, so customer cannot checkout -> show message
            response.redirect "msg.asp?message=206"
        end if

I would put the new code very near there.
