can't see fields/data

[sinnetbs]

Hi. I'm relatively new to Filemaker - a warning.

I imported records into a database, creating fields as I imported. The database indicates (via grey horizontal bar on the right) that there are 20 fields, 400 records, but nothing shows up in the actual viewing area. I do have "show all records selected," and when I click on define database again, all the correct information is in there. It doesn't matter what view I'm in (layout, browse, etc.), it just shows blank white space where my table should be. I'e imported records before and haven't had this problem. Any help would be greatly appreciated!
