How to expose age range in views? I'm trying to add an exposed filter for an age range with the Views module.

I made a select age field for age 18 to 80, but I can't find how to add a filter range in views.
For Example, I would add a filter saying "from age__ to age__".
From the filter criteria choose the age field tick the exposed filter.
Choose grouped filters from the filter type to expose.
Choose the widget type. Then add values after changing the operator to 'is between'
