**Mike_G**To my understanding, this is what you're trying to accomplish

Here's what you can do to achieve that:

First: Add Matrix field to your form

Second, create row and column headers

Lastly, create the condition to perform equation. Do not forget to save the condition you have created before saving the changes you made to your form.

I hope this helps. Let us know if you need any further assistance. Thank you.

**BJoanna**If I understood you correctly you want to calculate Floor Total for all Floors.

To achieve that you will need to add matrix table with 6 rows and set calculation for each row like my colleague Mike mentioned on previous post. Then you need to add calculation widget to your form and calculate Total Floor of each row to get final calculation.

Here is my demo form: http://form.jotformpro.com/form/52712018668962?
