>My first suggestion would be to not use an array. There are a couple of reasons for my suggestion. Foremost among them is that a cursor is much easier to deal with than an array. I'm not against arrays, but for this purpose there is what seems to me anyway to be an easier way. The second reason is that using a cursor takes advantage of intrinsic VFox engine behavior. Using engine behavior where possible always makes application development easier, whereas duplicating engine behavior programatically always make the app harder to work with in the long run.

.BoundColumn takes on a numeric argument, not needed in this case, coz' RowSource is single field. Shouldn't RowSource read "curCatTypes.Cat_ID" ?
