    BMI Calculator Form Integration

    Asked by Travis Crawford  on February 27, 2017 at 04:01 PM



    I am building a new form for a client of ours. They are a medical clinic running a weightloss program. Eligibility to the program is dependent on the participants Body Mass Index. I see that JotForm has a BMI calculator that can be built into forms. But, is it possible to continue the form based on the results of the BMI calculator? For example, if the user has a BMI greater than 32 it would continue on to the patients form, but if their result is less than 32 is would end the form there?
