Multiply the value of 2 entities

1
Hi, I'm new here and would like to ask for help. I am learning to use the Mendix application and I would like to know how I can multiply the unit value of a product by the quantity. I would like to present this multiplication in a TextBox. In the image below, Marked in yellow: I take the "Valor Unitário" multiplied "Quantidade" and in the "Valor Total" field I hope that the value of this multiplication appears, however, it is not appearing.

Try adding an “On Change” event handler on the Text Boxes for "Valor Unitário" and "Quantidade". In this microflow, set the value of the “"Valor total" to be the result of the multiplication.

Hi Robert, Please can you help me again with microflow. I did as you suggested, however, I didn't get the result in the "Valor Total" field. If I'm doing it wrong, can you correct me please.
