Any integer is an acceptable value for a spinner (the Microsoft
recommended range is from -32,767 to 32,767, but you can set it up to
go higher). I have just set one up that goes up to 100,000 without
problem. I imagine that the emphasis here is on the word
"recommended".
There are two spinners. The one from the Forms toolbar is limited to 0 to
30000.
But if you're trying to allow the spinner to go from 25000 to 350000 (say), you
could use a limit of 0 to 5000 and a helper cell that adds 25000 to the linked
cell.
Or if the spinner is on a worksheet, you could replace the forms toolbar version
with the spinner from the control toolbox toolbar version.
