Wizard AX 2012 R2

Hello guys,

I created a wizard and in the step1 the user should select a customer. Then in the second step I wanna show the invoices in a grid for the customer selected. The user could mark some invoices and when the user select one (or some), i wanna show user in a textbox the sum of the Amount of the invoices selected.

I just have the step1.

How I do the second step that depends of the AccountNum selected by the user?

Please help me.



nobody can help me?
