Hello All, I have tried to intergrate the VAT hook but still got problems. Edit the file like this: $VAT_CUSTOM_FIELD_NAME = "VAT Number"; $VAT_HOME_COUNTRY = "NL"; add_hook("ClientDetailsValidation",0,"checkVATNumberIsValid",""); add_hook("ClientAdd",0,"setTaxExemptForVAT",""); And make a custom client field named VAT Number, but when i order and i say i'm from Belgium and i use a BE VAT Number the system says: The supplied VAT Number is not valid But when i do this check in the browser: http://isvat.appspot.com/BE/0447830192/ the output is true, why would WHCMS say that the vat number is incorrect?
