Product combinations and quantities (PS 1.7.6)

[onewhite]

Hi Guys! 😀

I have a query i hope someone can help with.

In this scenario, lets assume I have:

• 1 cake for sale
• you can add layers and each layer costs $10

I can easily set this up as a product to purchase in my store, and use "combinations" to have different values/prices for adding on a new layer.

So it would appear in that section as:

1 cake, 1 layer  $10
1 cake, 2 layer  $20
1 cake, 3 layer  $30

The quantity I have to set for each is 1, as I only have 1 cake.

My problem is, if someone buys "1 cake, 2 layer" - that quantity decreases to 0, but the quantities for the other two remain as 1.

But I don't have that cake to sell anymore... so each time, I have to go into this product, and reduce ALL the combinations to 0 for this sold cake. Because, they can't buy "1 cake, 3 layer" because that cake has already been sold.

Am I doing this wrong?  I want ALL to reduce to 0 when someone buys ANY of the combinations, as that cake (and all it's combinations) are now zero - until I make another cake to sell.

I hope that makes sense.

Please let me know if there is a simple solution to this.

Thank you!
