Calculation in kobotoolbox

Hi community,

I am developing a tool on kobo and i am getting an error message below:

FormLogicError: Could not evaluate: Total agricultural income, message: not sure how to handle expression called on nodeset that doesn’t start with a ‘/’: agriculturalincome{“stack”:[{“t”:“root”,“tokens”:[{“t”:“arr”,“v”:}]}],“cur”:{“v”:“agriculturalincome”}}

My form link is below: https://kf.kobotoolbox.org/#/forms/avPBrGiW42hzWdTbNigA78/edit

I want a formula that will add up the income reported in E1, E2 & E3.

Kindly assist.

Hi @kenyaprogram2023
Welcome to the forum.
I checked your form and noticed that the calculation has been placed in the wrong section of the form builder. Please take a look at this documentation article for guidance.

Good morning,

Where should I place the calculation because i wanted it to sum E1, E2 & E3.

Please guide.

Andrew
