Poor Guys Bug disables the stock quantity max / min values

I believe the problem is located in wcpgsk-fa.php which rewrites the quantity input

Fixed it for you. it’s in the -af file. I’ve also tidied up the function for you, as well as the min and step functions. And try not to use : endif instead of { } as it’s more to type, and less readable. Also there’s a typo in the step function, whatevevr which i’ve fixed for you.

			$options = get_option( 'wcpgsk_settings' );

				$maxqty = 1;

Hey guys,
did you check that if two users put the same product with stock qty 1 both the users are able to conclude the order going to stock qty -1?
