If you would like this value to be computed for you, you can use a Hidden
Value to represent the difference (instead of an input question), and then
setting the expression you have to take the difference as the
for that hidden value.
If you want to display the result to the user, you can create a Label and
drag the new hidden value into its display message to the user.

of those two numbers.
Enclosed is the screenshot of my form.
When I try to get difference it is giving me a warning and also it is not
calculating the difference in the form.
