>I know that's the situation that usually causes that error. I'm pretty sure that the field should accept the values, however, since I took table a, copied it's structure to table b. I'm then scattering certain records from a, and gathering them into b.

Josh,

Suppose, you have Field1 N 5 in Table 1. Try Browse for Field1>99999 and see, if you get something. I believe, you have Data problem, not bug in scatter/gather. As another alternative, you can try scatter name loTemp.
In this case you would not mess with variables at all.
