Here you can see that I have some fields in my database with numerical names, e.g. 2004, 2005, etc.:  There are 380 items for which the field "2005" = Yes.

 

 

But when I double-click the "2005" field name in the All Fields list to bring up a Scratch grid containing those items, I get this:

 

 

The Source of the Scratch grid is "IDItem=2005" and accordingly, only that item is displayed in the Scratch Grid.
