**HOWNewForms**Still need to work on the calculations. I've tried both the Excel formula (Column/Row d1 "=b1*C1") and Mike G's formula in earlier response of d1 = b1*c1 and neither get saved.**Carina**I inspected the form and the Spreadsheet didn't have any default values (formula) added:

To add a formula to this widget please select the wizard and then add the formula to the "default values" area as seen bellow:

**Formula**d1 = b1*c1

d2 = b2*c2

d3 = b3*c3

d4 = b4*c4

d5 = b5*c5

d6 = b6*c6

d7 = b7*c7

d8 = b8*c8

d9 = b9*c9

d10 = b10*c10

d11 = b11*c11

d12 = b12*c12

d13 = d1+d2+d3+d4+d5+d6+d7+d8+d9+d10+d11+d12

You can test and clone the demo form:

Let us know if we can assist you further.

**George Chrisman**Thanks for the solution. I read the box as "Optional" and never saw a notice that default values had to be applied.

**ashwin_d**Helo George,

On behalf of my colleague, you are welcome.

Yes the "Default Values" property of the "Spreadsheet" widget is optional but needs to be added if you need to display or add some calculation formula.

Do get back to us if you have any questions.

Thank you!
