I am thinking of doing the following for my website, but I am not sure how to do so / whether it's possible.
I am using 123 Form Builder to collect data from the visitor. On the same webpage, I have text fields, containing numbers, that I wish to update according to what the visitor inputs in.
1. The user is supposed to input two dates on the form. I want the my text fields to update to the chosen dates. E.g. if the user picks 17/03/2018, then the text field will update to 17/03/2018
2. I want a text field to update to the number of days in between the 2 dates. E.g. if the chose dates are 19 and 20 March, the text field will update to 2 days.
3. I have a "total cost" that is a result of # of days (from my previous question) multiplied by a number (a predetermined cost per day). I want this text field to update as #1 and #2 happen.
Looking forward to hearing from you!
If it's not feasible to do so, any suggestion on how to better execute this workflow would be much appreciated. Thanks!
