Calculation - power (BMI calculation)

[Giul]

Hi everyone,

I need support to get the writing of the formula right as it gives me error. I need to calculate the BMI in the form, as : weight/(high)2

In the XlS form I write the following:

${weight} div (pow(${high}, 2))

What is wrong? Hope the post might be helpful also for others.

Best

@Giul, this post discussed previously should help you solve your issue:

Fomula for finding BMI

@hhfoffice, you could do it by adding an if-statement as shown in the image below: In the survey tab of your XLSForm: [Image 1] Data entry screen as seen in Enketo: [Image 2] Reference XLSForm: Calculate BMI.xlsx (9.2 KB)
