How do i calculate the difference between to times. For instance, how much time passed from 8:30AM to 3:30 PM?
How I can calculate total number of jpg files upload in form and the number that still remains to add 100 files. I want to make a form for printing photos up to 100 files.
How can I calculate the number of hours worked based on time
Hi, I have this big equation that I am trying to put on jotform calculations and it doesn't seem to work. Would you be help out?
In the places of F4, E4 and D4 i would number fields to fill in.
=495/(1.0324-0.19077*log10(F4-E4)+0.15456*log10(D4))-450
min function not working even on the template provided above.
Is it possible to lock this widget so that a form user cannot mess with the formula calculations being done? I can ask them to not reconfigure the math completed in this field, but it would just be easier if they just didn't have the opportunity to do so.
Thanks!
How can I calculate a duration (difference of two different hours)? Thank you.
