                        var btnVars = btnString.split(' ');
                        var lenMinOne = btnVars.length - 1;
                        var lenMinTwo = btnVars.length - 2;
                        globPrice = globPrice || parseFloat(btnVars[lenMinOne]);
                        //if(globCount == 0){globCount = 1;globPrice = (globPrice * (100/75)) - (100/75);}
                        var vprice = (globPrice - (globPrice * (parseFloat(attribute_value['subscription_scheme'].discount)/100))).toFixed(2);
