I want to create a form where there will be 4 inputs per page. It will be like 20 pages. I have to make sure that the total number of the entered input values are 10.
page1
input1: 2
input2: 0
input3: 5
input4: 3
page2
input1
……
in case it is not 10 i should display an error. Is there any smart way to get those 4 inputs for every page and add a custom validation to it?
In your example here, for page 1, that total is correct and the visitor should be advanced to page 2, correct? But if the total is incorrect, not 10, they should be shown an error?
You could do this with the gform_validation filter. http://www.gravityhelp.com/documentation/page/Gform_validation
Check the total of the values entered for those fields, and return an error on that page if the total is not 10.
You could also do it before the next page is selected, using jQuery. Here is one solution I found for adding up field values http://www.devcurry.com/2010/04/sum-of-all-textbox-values-using-jquery.html
