      Dear Ali,
It seems to be a simple task. First, as far as I know the BMI is calculated
as weight/(heigh*heigh). However this values should be in Kg and m. If you
have the data in pounds and feet, then youl should transform them before. To
make it easier, create a variable in the qes file with this information.
qes file
v1      heigh in feet ##.#
v2         heigh in m #.##
v3 weight in pound ###.##
v4      weight in Kg ###.#
v5                  bmi ##.##
chk file
v1
  after entry
    let v2 = round(v1*0,4536)
  end
end
v2
  noenter
end
v3
  after entry
     let v4=round(v3/3,28)
  end
end
v4
  noenter
end
v5
  before entry
    let v5=v4/(v2*v2)
    goto v6
  end
end
I hope this works fine for you because didnt test it! ;)
Succes,

Thanks.
I just recently started using Epidata, and I need some help on creating a
Check string for automatically calculating BMI using Weight and Height (in
pounds and feet/inches). Thanks, again.
