Setting Maximum Quantities

Hi, I need to set items so the online buyer cannot order more than a set maximum per item. For instance, a site that allows sales reps to order catalogs would not be able to order more than 25 of a particular catalog. How do you suggest I do this so that if they attempt to put in more than 25 in the quantity column, it will not let them do so.

Thanks!

I would create a column in the cart called MaxQty.

Then I would create a calculation:
TrueQty = (([Quantity]<[MaxQty])?[Quantity]:[MaxQty])

Finally I would Update the TotalWeight and TotalPrice Calculations to:
TotalPrice = (([Quantity]<[MaxQty])?[Quantity]:[MaxQty]) * [Price]
TotalWeight = (([Quantity]<[MaxQty])?[Quantity]:[MaxQty]) * [Weight]

Then wherever I display the quantity I would display the MaxQty instead.

Thanks Ray, but when you say where ever I display the quantity you would display the max quantity instead. Where? And in your code, where do I put the max qty amount, for example 25, how does the software know the max quantity. Please forgive my ignorance. I truly appreciate your help.

You would update the add to cart button to set the max quantity.

Probably the only place you display your quantity is on your cart page, your confirm page, and your pp_confirm page. So just find anywhere on those pages where it has ->displayInfo("Quantity")

and change it to:
->displayInfo("TrueQty")

Thanks Ray, but I still don't understand how I code in that a buyer can't buy more than 25 of an item. Where does the number "25", for instance go in the code that you wrote?

You added MaxQty as a column to the cart... this means in your add to cart button you can specify a value for it. Specify the value of 25.

Yes, I can see where you can specify the value, but can I specify a max value in the "add to cart" button so that it won't let them order more than the 25. I also wouldn't want it to populate 25 automatically. For instance right now all the defaults are set to 1 per ecart's instructions, I would not want the default set to 25, but rather the customer not be allowed to order more than 25. Sorry for sounding so ignorant.

Just try what I am telling you.... it would still say 1 in the quantity field. Just if they typed more than 25 it would only show 25 in the cart once added. They could change it to a lower number, just not a higher one.

What I am telling you to do will accomplish what you are trying. Please try it and then describe what you might not like about this solution. Your arguments against this technique do not seem valid.

Ray,

Honestly I am not arguing just very confused! You are a great help and I appreciate everything! I will try it and let you know.

Thanks!!!

Ray,

I added the column "maxQty" to my cart. Now in the bindings on the "Add to Cart" do I put 25 in the default value for the maxQty? Also do I make it updateable and as a text field? Then would I adjust the shopping cart page to display a column that says Max Quantity?

You also said you would just display the maxQty, so do I disable and delete the Quantity column from the bindings and the shopping cart page?

Again, I am just trying to understand and appreciate the help!
