Setting a minimum order value by country for Catalog V5.

This will allow you to specify minimum order values for a list of selected countries 
and a default minimum for countries that are not in that list.  
You can have a minimum of 0 for a particular country, or for the default minimum.

Customers will be blocked from moving to the payment stage of checkout if they are below 
the minimum for the selected delivery country.  A meaningful error message will be displayed.

In the example below we have minimum order value of £10 for United Kingdom,
£20 for Germany, and £50 for any other country.

Instructions:-

Go to Catalog / Advanced / Custom Properties 
Click the "+" sign and create a new CustomVar called DEFAULTMINORDER
Again  click the "+" sign and create a new CustomVar called COUNTRYMINORDER
Ok out.

Double click the top level of your catalog and choose Advanced
(if not already showing Properties).  Select Custom Properties.
Select the property DEFAULTMINORDER and set it to whatever you wish you default
minimum to be in your usual currency.  E.g. Set to 50 for £50.00
You can set this to zero if you wish.

Select the property COUNTRYMINORDER and set it to a comma separated list of countries and minumiums
in the following format.  E.g.   "United Kingdom", 10, "Germany",  20
Again a country can have 0 set as its minimum.

Ok out.

You must obey this format exactly or you will get a server error on checking out.
Keep quotes around the country names.  Use numbers ( like 10 or 12.34 )for the amounts.
The country names need to match those in the list you see when checking out.
You can have as many pairs of entries as the 256 characters that CUSTOMVAR's allow.

look down some lines 'till you see

	$nTotal = $SummaryResponse[6];
	#
	#	1) If (total == 0 || prices are off)
	#		If (user defined field is hidden)
	#
	#			mark payment complete
	#			mark method pre-pay
	#			skip processing
	#
	#		else If (user defined is not hidden)
	#
	#			mark method pre-pay
	#			hide payment stuff
	#


immediately after this ADD the following code



	my $nMinOrder = CUSTOMVAR:DEFAULTMINORDER;	# (V11)
	my %CountryMinOrder = (CUSTOMVAR:COUNTRYMINORDER);
        my $sDelCountry = ACTINIC::GetCountryName($::g_LocationInfo{DELIVERY_COUNTRY_CODE});

	if ( exists $CountryMinOrder{$sDelCountry} )
		{
		$nMinOrder = $CountryMinOrder{$sDelCountry};
		}

	if ( ($nTotal / 100) < $nMinOrder )
               	{
		@Response = ActinicOrder::FormatPrice($nMinOrder * 100, $::TRUE, $::g_pCatalogBlob);
		if ($Response[0] != $::SUCCESS)
			{
			return ($::FAILURE, $Response[1]);
			}
                return ($::FAILURE, "Minimum order value for " . $sDelCountry . " is " . $Response[2]);
                }



Save and update your site and that's that.

You can maintain the countries and minimums by altering the Custom Properties DEFAULTMINORDER and
COUNTRYMINORDER in the top level of your catalog.
