How to call a Class Method

[srfpala]

In this project, I have a form (frmSales in the Pres Layer) which collects the sales transaction data.
I have a class called SalesTran in the DataLayer which has a method called SerializeTransaction() which
is to be called from frmSales
These live in a project called Ch12RnRBooks
As I key into frmSales " Call SalesTran.SerializeTransaction() "
I get an intellihelp message bubble showing the line below
Public Sub SerializeTransaction(SalesTran As Ch12RnRBooks.SalesTran)
This argument makes sense to me since I want to invoke the SerializeTransaction method of the SalesTran class.
However, as it suggests, I insert the argument ( shown below)
Call SalesTran.SerializeTransaction(SalesTran As Ch12RnRBooks.SalesTran)

It responds by saying that SalesTran is a type and cannot be used as an Expression.

Anyone see what I'm doing wrong ???

The method wants an argument of type Ch12RnRBooks.SalesTran, so you have to give it something that is of that type.
For a method Sub Say(message As String) you would give it a string like this: Say("hello").
