Thanks Jimdandy,

You mean's first we need to select order number then we can use OrdersType() in my if statement.

 when i have 2 orders and i use 

Alert("You Have ",OrdersTotal(), " Orders");//Get All Open Order in Alert Message

 Alert message show correct numbers of orders but when i modify the order then it show Ordernumber 3 modify.

So then i thought

OrdersTotal()==1 && OrdersTotal()<2 && OrdersTotal()!=2

 is not work properly because after modify order we have the numbers of orders 3.
