You'll need to tell us more.
What options did you use when exporting the records?
To what file type did you export?
I was exporting into .fp7 files so that I could immediately re-import them, other options selected were no dialog. I remedied the problem by using the "update matching fields" and throwing in a match field. I still get the extra exported records, but I don't reimport them. I think it may be because I was exporting related records rather than the records on the layout I was running the script from.
Any chance those extra records exist in your Filemaker files before you try the export records operation?
Yeah, exporting the related records may have been the issue. Try it from a layout based on the table of records you want to export.
These extra blank or almost blank records on text export has been a problem in Filemaker 8.5 and before. I have submit a bug regard for Filemaker 8.5.
We have recently upgraded to Filemaker 11. Apparently Filemaker has not addressed the problem over several updates and upgrades.
