Thank you for your response. I did have it set to update old records with new data. It turns out that the issue was the length of the entry id/issue id field. In prior versions of ARS, the field was 15 characters long. We've been on it since version 4.5 and hence had forms that had the longer field length.
The core field 1, reserved for entry id numbers, is 8 characters long in the 8.12 version. Since we are migrating rather than upgrading (which preserved the existing column definition length apparently), the import tool, instead of truncating the data in the entry id field, used a default fall back mapping to auto increment (though a fall back mapping wasn't set). So I guess I'm off to go truncate some leading zeros!!! _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org "Where the Answers Are, and have been for 20 years"
