>>Bret, VFP3 has problems handling numeric fields in Combo boxes. You may be using your IDs as the bound field in combos, particularly for lookup tables. Using Character fields avoids the problem, and it's easy to use a PadL() function to stuff leading zeroes into the character field.

Bret, not for the users to see. In a lookup table, I often store the key field value, but want the user to see the description. In the combo, VALUE is the key field, DISPLAY VALUE is the description.

Hope this is clearer,
