Update more than one selected records ?

Update more than one selected records ?

Hi experts,

How to update Status = "Paid" where Invoice_No = "test" ?

BTW, I managed to update 1 instead of  3 records using the script below:

Please advise, many thanks. :)

1. // Assume rec = "test"
   
2. rec = Invoice[ID == input.Invoice].Invoice_No;
   
3. 
   
4.     for each sel in Delivery_Order[Invoice_No == rec]
   
5.     {
   
6.         UpdateStatus = Delivery_Order[Invoice_No == rec];
   
7.         UpdateStatus.Status="Paid";
   
8.     }
   

  Delivery_Order
