Instead of export, use Import to copy the data from one filemaker file to another. It sounds like these two files should have the same field names, so an import using the "matching names" option should work well in most cases.
If you must export the data into an intermediary file, try exporting the data as a merge (.mer) file. This text export includes the field names and you can use a "matching name" import to import data from this text file into a different copy of the same solution file. (That assumes you used single word field names for your fields, otherwise you'll have to manually align the fields by name during import.)
Thanks for the tip..... It works.....
Much Appreciated PHIL
