Maybe try something along these lines

Make the spinner settings as:
Current value: 10
Min: 0, Max: 20
Cell link: A1

Put in B1:

=IF(AND(A1=0,A1<=10),(A1-10)/100,IF(AND(A110,A1<=20),(A1-10))/100)

Format B1 as percentage, to zero dp

Now try clicking on the spinner's up arrow:
B1 will increment in steps of 1%, viz.: 1%, 2% ... 10%

Clicking down decrements B1 in steps of 1%
and will enable B1 to show (past B1 = 0%): -1%, -2% ... -10%

As before, we can now point other formulas to B1 as the spinner output
(instead of A1)

Nope. Still did not work.

Here is what I've done

Problem: To evaluate +/- change by spinning 1% up or down.
Set A1=1; B1=100
Set A2=(A1/B1)%
Assign Spinner to Cell = A1

As soon as I assign spinner to B1 = a negative # (as you suggested)...after
the first spin the number goes to zero and only goes up!
Hope this helps.
