Biting off too much and overcomplicating

I want you to create a website calculator by generating the code that I can copy to a wordpress page that will render a calculator where users can provide inputs and then get a calendar output they can download as a pdf or similar file. We’ll call this website tool: Media Planning Calculator. To begin, we need a field where the user can put in the total budget for the year and this should be a simple text box. We then need three fields under a section labeled “Initiatives” and those three fields are for Awareness, Consideration, and Conversion with a text box next to it where a user can input a percentage amount to represent what percentage of the total budget needs to go to each “initiative”. We need to trigger a warning message if the 3 values entered into these fields equal something other than 100. We then need a section of this calculator where users can select “Channels” from a drop down selecting under each “Initiative”, up to 4 channels each. The default options from the dropdown should be Meta, Paid Search, YouTube, and Display. Each of these “Channels” should serve as a row with a box to the right where the user can enter a percentage amount. This will take the budget provided for that Initiative and divide it to that channel based on the percentage provided. We need to show an error message if the percentage amounts under each Initiative do not equal 100. This should provide the user with a monetary value to the right of the percentage field showing what the budget for that channel is. This section is for users to add rows for each Product/Service they’ll be advertising under the 3 Initiatives outlined. The default number of rows should be 6 rows under each Initiative subsection with an option to add a new row. The user will label the row in a text field in what will serve as column 1. In a second column, we’ll call that column 2 internally, they need to provide the dates this product/service will be run. Then in the 3rd column, I’d like to label this as “Percentage of Total Budget” users will put the percentage of the total budget of that Initiative that they’d like to allocate to that Product/Service. This should fire an error message if the values in each subsection don’t total 100. Once a value is entered there should be a numerical value displayed on the right of the row that represents the percentage entered into the field multiplied by the subsection budget outlined in the first section.
