Can't sum from numbered drop downs?

[patchesohouli]

Hi, I have a bunch of drop down boxes with number options. When I create a calculation field, I apparently can't select those as fields for the program to sum. Can anyone assist?

It should be possible... If it's not you can always use the Simple Field Notation option, or the Custom Calculation Script option.

The former can be used like this:

DropdownBox1 + DropdownBox2 + DropdownBox3
