How can I add the options in the fieldAsked by abdullahhajar827 on February 14, 2015 at 10:39 PM
how can I add the selected options in one field (in drop menu or check box). then to use the total of this field in the calculation of the general total
Here's how you can do a calculation in the form: http://www.jotform.com/help/259-How-to-perform-calculation-in-the-form.
I saw that you have already figured out on how to add a calculation value. However, you cannot add the fields to it so I have removed the formula. And for the "Options" field, I would suggest using Checkbox Field instead since you would like to calculation the multiple selections.
I've cloned your form and made these changes, check my form here: http://form.jotformpro.com/form/50451081319953?
