>Did the import of this table go without problems? Could you see this fields content in the preview of the import? If this is a free table (or even if it is in a database - you could detach it) please send me a few records - I could try to see where is the problem

Yes, it went well. No, I was not seeing that field in the preview. The test table I used is very small. I will send it to you by email and you'll be able to tell me if you get the same behavior.
