I am creating a medical transcription website. Since I will be charging my clients per minute and per hour, not per report, I need to create a transcription cost calculator that will allow my clients to calculate the total price per report. However, in order to add the calculator to my website, I need to create the HTML, and I do not know how to do this. The cost calculator would need to look something like this:
Minutes of recorded audio (a window would be displayed here, where the client can indicate the number of minutes of their report (from 1 to 60 minutes).
Hours of recorded audio (a window would be displayed here where the client can indicate the number of hours of their report (from 1 hour to 60 hours).
Total cost (here the total cost of the report would be indicated).
Depending on whether or not you want to save the data of your clients (so you can refer back to them in the case of recurring clients), what you're thinking of may be a bit more complicated than just html.
But if you want to store data, you'll need to add backend stuff, like php and mysql.
