[AccessD] TransferText Puzzle

TransferText can be a bit flakey.
The missing fields in the second record appear to be in the same place as Date and 
Numeric fields in the first record.
I'd suspect that TransferText is trying to convert these fields in the second row to numeric of 
some sort.

Two possibilities:

1.  Create and use an Import Specification which explicitly defines all fields as strings.
2.  Get rid of the TranferText and do it yourself so that you have full control:

(Aircode)
     Open strFullFilename for Input as #1
     set rs = currentdb.openrecordset("ttmpTemporary")
     DO While not EOF(1)
        Line Input #1, strTemp
        strFields() = Split(strTemp,",")
        rs.addnew
        for x = 0 to ubound(strFields()) 
               rs(x) = strFields(x)
        next
        rs.update
    Loop  
    close #1
    close rs
    set rs = nothing
