I have the following problem.
I would like to have a form with 5 fields.
The first 4 fields will be used for data input form the user.
For example, a user will type:
·
Value “12” in Field1
·
Value “14” in Field2
·
Value “8” in Field3
·
Value “5” in Field4
In the fifth field, I want to show the sum of the values of the 4 fields
Thus, in the above example, I want to calculate the sum (Sum=39) and display the sum in the fifth field.
How can I do this?
