Little generic arrows (id 201317)

[Prodevm]

Hello,

I am trying to associate the Little generic arrows (image ID 201317) with a field, to display a range in the set numbers (1-30) when clicked up or down.  I have set the cTargetField to the field name, and I have set MInValue and MaxValue for the arrows button.  However, when I click the arrows up or down the number displayed in the field does not change.  Do I need to put something in for the script of either the button or the field?

Thanks

Steve
