I would like to make a sum of all dropdown values into a label text box.

I am using following formula, but I do not understand where am I going wrong.

Can anyone assist?

I have also added a screenshot if that helps anyhow.

Note: scores is the table name the dropdown values feed from.

Sum(scores, Dropdown3.Selected.Value + Dropdown3_1.Selected.Value + Dropdown3_2.Selected.Value)

  • Have you tried formula in answer? Can you share screenshot of error message? Commented Dec 2, 2020 at 7:16
  • Hi ganesh, yes I've tried both formulas. I do not think it is formula error but something else. I have emailed a picture with error message.

    I think there is issue with the drop-down controls in your form or in SharePoint connector. Try refreshing SharePoint data source, removing and re-adding dropdown controls in your form. Commented Dec 4, 2020 at 15:22

Set the Text property of label to:

Sum(Dropdown3.Selected.Value, Dropdown3_1.Selected.Value, Dropdown3_2.Selected.Value)

If data type of selected item value from drop-down is string then use:

Sum(Value(Dropdown3.Selected.Value), Value(Dropdown3_1.Selected.Value), Value(Dropdown3_2.Selected.Value))

Microsoft documentations:

  1. Sum function
  2. Value function
