On the checkout Payment page in osCommerce we have a field that collects Credit card Number.\r\n\r\nThe number displayed On credit card looks like this \r\n\r\n4111-1111-1111-1111 or 4111-1111-1111-1111\r\nNormally user would like to fill it that way. \r\n\r\nNow if a customer fills osCommerce Payment form this way i.e. with spaces and in between credit card numbers, Either it may be blocked by java script validation  or the following message will be displayed. \r\n \r\nWe do not accept that type of card \r\nThis error can be avoided by removing the spaces or \u2013 while filling the form and then validating it. Small changes can make osCommerce shopping cart more user friendly.
