negative quantity balance - major problem

Hello JS forum

My buyers are able to order more quantity than the balance of the product item

eg stock quantity (before order) 4; order quantity 7; stock quantity (after order) -3

it should not let the buyer order more than 4 with a message stating cannot order this quantity, order a lower quantity

please help as I am sure this function was working in the past

I am on JS 4.11.6

thank you kindly
regards Nick

thank you
I used option 2
that does work as it gives me this message

Error
Some products can not be delivered in the quantity ordered
The maximum order quantity is 2.

However it reveals to the buyer how much stock is available
How can I remove the 2nd line
