Count Checkboxes with Gravity Forms

问题

I'm making a form that is for a summer camp registration form where users will be registering. By the end of the form there is an option of paying in full or making a $50 deposit for each camp selected. I'm using hidden products to handle the total amount per week and adding their value into the total. My question comes if I can use formulas to count the number of checkboxes that have been selected and do the calculations.

Example:

Week 1:

• Soccer camp

Week 2:

• Computer camp

Total: $100 (Deposit)

I actually have a snippet for this:

The parameters are:

• form_id the ID of the form for which you would like to count the checkboxes
• count_field_id the ID of the field into which you would like to populate the checkbox count (you can then use this field's merge tag in a Calculation formula)
• checkbox_field_ids an array of Checkbox field IDs whose checkboxes should count towards the checkbox count (when checked)
