I can see that it is an invalid expression.

I tried it with a new formula, which seems to be valid.

However, it still doesn't show the calculation of BMIP and it appears that even though I fill in the questions they are registered as if there were not displayed.

Ok, i have been working on it all day and I now know where my problem is:



My problem is with the BMI based on feet-inches and pounds (BMIP).



First: BMIK (centimeters and kilograms) is going fine:

formula BMIK: (x/ (( y/100)*(y/100)))

and

formula embedded data BMIK:

$e{ ( q://QID5/ChoiceTextEntryValue ) / ( ( ( q://QID4/ChoiceTextEntryValue ) / 100 ) * ( ( q://QID4/ChoiceTextEntryValue ) / 100 ) ) }





Also, the formula for BMIP is fine: I can see that it calculates the right numbers for BMIP:

based on the formula BMIP: ((x/(((y*12)+z)^2))*703)



But then the problem is with the formula for embedded data....the embedded data of BMIP all show 0 zero, so this does not match the formula somehow.

$e{ ( ( q://QID3/ChoiceTextEntryValue )/ ( ( ( ( q://QID1/ChoiceGroup/SelectedChoices ) * 12 ) + (q://QID2/ChoiceGroup/SelectedChoices ) )^ 2 ) * 703) }



Can anyone see the error maybe?

@Loes

Doing a quick look at your BMIP formula, and it looks like you are missing spaces before and after 12 for QID50 and after the QID51 multiplication sign.





It should read (with some short hand) q://QUID52 / ( ( ( QID50 * 12 ) + QID51 ) * ( ( ( QID50 * 12 ) + QID51 ) ) ) * 703 )



Note - I tried to bold or underline the spaces, but it formatted poorly.

I think it should be:

```

$e{ ( ( q://QID3/ChoiceTextEntryValue ) / ( ( ( ( q://QID1/ChoiceGroup/SelectedChoices ) * 12 ) + ( q://QID2/ChoiceGroup/SelectedChoices ) ) ^ 2 ) * 703) }

```

I added three spaces:

1. between q://QID3/ChoiceTextEntryValue ) and /

2. between ( and q://QID2/ChoiceGroup/SelectedChoices

3. between ) and ^

Thank you! It worked like this:



(x/(((y*12)+z)^2))*703



$e{ ( q://QID3/ChoiceTextEntryValue ) / ( ( ( ( q://QID1/ChoiceTextEntryValue ) * 12 ) + ( q://QID2/ChoiceTextEntryValue ) ) ^ 2 ) * 703 }
