Hi Guys

this will just be a quick fix for someone out there but i'm not sure where is best to put my code; The problem is that when you have donation products on the site if you put a negative figure in the amount it will reduce this from your bill and then allow the order to go through with the invalid reduction.

Does anyone know where i might put a validation for now allowing negative figures? thanks in advance for any help.

Hi Brad,

I've just looked at the code for donation features and you're right, there is no check for a negative amount entered. If you open shopproductfeaturesprocess.asp and find the sub routine:
Sub ProcessUserPrice
Then find the line:
If not isnumeric(price) then
Add a negative check here so change the code to:
If not isnumeric(price) or isnumeric(price)<0 then
You may also want to change the wording of the error message that displays to alert that negative numbers cannot be entered.
getlang("LangUserPriceError")

I've tested this and it works fine.

Regards,
