Mark, this works with strings, but not numbers. The real key here is to either set the filter to reference the spinner using a continuously-resolvable reference (IOW, rather than thisform, use whatever the current member of the _SCREEN.Forms collection is, so that when you move out of this object, the reference can still be resolved) or to insert a literal of the appropriate type in and use macroexpansion to set up and resolve the filter value; this has the problem that you have to completely reset the filter whenever the value is altered.

A better approach might be to use a parameterized view; whenever the vlaue chaged, update the parameter variable and requery. Since this is not tied tightly to the control, you're fine as long as you reset the variable and requery the view whenever this value changes. this gets around all the problems of mcroexpansion pretty well, and gets away from one of the constructs that I try to avoid, SET FILTER.
