[mv] Newbie: External CC validation

{ HYPERLINK "mailto:Minivend-users@minivend.com"; }Hi All,

I was wondering is someone could help a newbie with Minivend 
4.02 and an external CC validation server.

I am trying to get Minivend to interact with an external credit 
card payment system of one of our French banks. This involves 
running a quick program which creates the form with all the 
security codes on it. This program needs variables passing to it 
like ‘total price’, ‘order no’, ‘ok URL’ and ‘error URL’.

All seems to be coming together but I am not too sure how to 
build the ‘ok URL’ section in Minivend. This is the one uses to 
fire the checkout after the payment has been processed. I am 
using the session id as in the following :

http://www.joe-bloggs.com/cgi-
files/blackup/process.html?mv_session_id=eZ2kxiqh&fax_order
=1&mv_doit=refresh&mv_nextpage=checkout&mv_order_profi
le=checkout_profile&email_copy=1&mail_list=0&quantity0=1&
mv_click=Place+Order%21&png=

which works ok. However when I change the submit button text 
to something else though, for example :

http://www. joe-bloggs.com/cgi-
files/blackup/process.html?mv_session_id=eZ2kxiqh&fax_order
=1&mv_doit=refresh&mv_nextpage=checkout&mv_order_profi
le=checkout_profile&email_copy=1&mail_list=0&quantity0=1&
mv_click=Order&png=

it simply refreshes the screen and does not run the ‘checkout’.

I am sure that it is not the text “Place Order!” which causes the 
checkout function to run. Could someone let me know what the 
bare minimum URL would be to trip the ‘checkout’ function into 
action.

Many thanks in advance for any help you can provide.

Paul
