Write some Software

We have built a website in Joomla 3 and which uses the Chronoforms V4.0.3 for all of the forms we have on the website. We have an [login to view URL] plugin that has been purchased and installed so that some of the forms function as payment forms. All forms currently are functional and work properly. We are looking to add some functionality to two of the registration forms, specifically to these two forms: [login to view URL] [login to view URL] Right now, both only have two payment options, member and non-member. A different form amount for this field is determined based on what is selected here. We would like to instead change this to add more options for each form. The changes are: 1. The form will ask if a person is a member or a non-member. Depending on what is selected will change the values of the fields in the next part: 2. The form will offer check boxes for 5 different options, day 1, day 2, day 3, day 4, and all four days. If multiple options are checked, i.e. day 1 and day 3, the payment amount field (which should be visible to the user on the form somewhere) should add up the dollar amounts. The person should not be able to select day 1 AND the all four day option. If the all four day option is selected, day 1 should not be added to the total. The total should never exceed what a person would pay for the four day option. Requirements: 1. The form has to remain in Chronoforms as long as the above functionality is supported. From all of their documentation, it seems it is since you can do custom PHP and Javascript. You are more apt to be a winning bid if you have extensive Chronoforms experience. 2. The rest of the form has to remain intact as-is as well as the existing integration with Authorize.Net. 3. Please do not contact us using any of the website contact information. We are the site developer. I've attached the pricing options that will be available for each of these form for reference in determining your bid.
