Large formula and calculated result on button submit in same page

Hello @anilvermapes,

The equation includes unnecessary parenthesis but it is correct:

((fieldname2/fieldname3-1)-fieldname2/fieldname3*95)*1.29*fieldname1*25*12*3

However, I cannot check the fields values. For example, if the fields values are not numeric or the fieldname3 value is zero, the equation will fail.

About submitting the form and display the result directly on the page, you will need the commercial plugin version.

Best regards.
