  • What’s the matter?

  • I tried this code but nothing appears on the label and when I click on the label the program hangs, I would be grateful if some experienced programmer can help me.

  • Hard to play local error post error too

  • You need to treat txtMoeda7.Text and txtMoeda8.Text. To not pass null values .. if(String.Isnullorempty(txtMoeda7.Text)){ valor7= 0}

  • Thanks Danielle Arruda Torres, your code tip solved my problem.
