I have a form that displays a stock inventory, one of the fields I use is called [ItemCode].

On the Stock_Inventory form I have 10 command buttons that open other forms to display additional product information.

These were previously sub_forms that sat in a tabbed control box within the Stock_Inventory Form but as it now takes a while for the form to load (lots of queries running each time you search for a product) users are getting slightly frustrated.

So, what I decided to do, was move each subform from the tabbed control into a new form and open that form when it is needed by the user.

OK, when I open Stock_Inventory and search for a product [ItemCode = "ABC123"] and then want to see the Sales_History, I have to open my new form, Stock_Inventory_Sales_History, within this form are two sub-forms, each subform has a field called [ItemCode].

However, when Stock_Inventory_Sales_History opens it asks me to input the parameter [ItemCode] twice, I presume this is because the Stock_Inventory_Sales_History does not have a record source and that the subforms need [ItemCode="ABC123"] to run each query and return the data.

I need to pass the [ItemCode] from the Stock_Inventory form to each of the 2 Subforms that are on the Stock_Inventory_Sales_History form automatically.

Is this possible or is there a better way to do this?
 
Create a Control on the Main Form that holds the two SubForms. This Control could either (a) have Default value looking at the Form that is currently open OR (b) use the Form OpenArgs method.
 
Could you expand on that Paul, not sure how to do either of those?
