I’m currently working on a form to collect field nutrition data for research.
I want to collect anthropometric data with a one decimal accuracy.
The problem is : with the constraint formula, the investigator can enter data without one decimal, and it’s a real issue for the exactitude.
After multiple attempts, I had to enter data with one decimal, but zero is not a permit value (65,0 for example).
Finally, I lmust have the possibility to enter data with 2 digits and 1 decimal where zero is a permit valule.
Thank you in advance for your advices.
