I've a problem that was'nt solved as far as I searched for a solution:
We are selling cloth in a european country and the quantities are measured with a comma instead of a point. I managed to change the appearance of the prices in the shop so that prices are shown correctly as 10,50 Euro per meter. BUT:
I really need to set the comma as decimal separator also for the quantity! People go and override the shown minimum quantity with a comma-value and get a message stack output, that the item is in the shopping cart, but it wasn't processed correctly.
At least I need a hint / error message for the customer when he puts in a comma in the quantity field.
Does anybody know a solution like this?
I already found a forum post regarding this: http://www.zen-cart.com/forum/showthread.php?t=102569
But I hope it is ok to start this new as it should be a general customization question in frontend, I think.
