I want to calculate the pressure of a hydrostatic fluid column with p(psi)=0.052*density(lb/gal)*depth(ft)
I have created a form with fields to enter the input, but I need somehow to pass the information entered to the JS calculation to display the result.
How can you pass an entered field value to JS caluclation and show the result into another field.
Thanks
Jeroen
