Expression is expected in ExpenseManagement Tutorial

Question

Hi Anyone,
I'm new with BPM studio.
I found a issue of expression when I was learning the Expense Management Tutorial case. The details in the below:
Defining a Virtual Attribute in Activity 3. In step 9:
# The total attribute is the sum of every item's amount value. To have the total attribute return this value, it must be calculated by adding the amounts of all the items. Remove any existing code (a line with return 0 should be all that you find), and enter the following PBL code into the editor exactly as shown, including capitalization:
amount as Decimal(2)
amount = 0
for each item in items do
amount = amount + item.amount
end
return amount
After I copy these code to the editor in BPM studio, there shows four red error icons and said 'Expression is expected' and 'statement is expected'.. I don't know how to fix this.
Hope anyone can help me to solve this simple issue.
Thanks,
James

Does it likes my BPM studio does not support BPL?
