I’m a beginner with Bubble.

I have this formula working in Excel:

=ROUND(((C22-40)/20*((C9^0.425)*(C10^0.725)*71.84/10000)*0.739/C9-0.003)^0.5*0.7,4)

Essentially this calculates a body fat %. Which is expressed as a fraction but easily converted to a percentage.

In Excel it works as follows:

- 10 body sites are measured and recorded into cells as numbers with 1 decimal place.
- The 11th cell (C22 in the formula) is the sum of all 10 cells/numbers.
- The weight (C9) and height (C10) of the client are then put into 2 additional cells.
- The formula above then calculates the body fat % expressed as a fraction in a cell formatted as a %.

I have the formula working in JotForm as a calculated field in a table which is connected to the form capturing the 10 site measurements and the weight and height.

**Bubble.**

I have put the formula into a Bubble workflow using the “Math Calculator” plugin.

I am trying to use a form to capture the 10 site measurements, then calculate the sum of the value and then apply the formula.

BUT… it doesn’t work. It is returning a zero. I have no error alerts.

I have not been able to get any help on this issue at all so any help or input would be much appreciated.
