If you want to let Access do the validation, then use a numeric field. That way, Access will check for you.

But if you want to do your own validation, then it is better to use a text field and extract from it. You will have the advantage for range checking, say you limit it to less than 10000, you can check the text length if greater than 4, error. Not only that, user can enter 9999999999999999 and that way out of range for any data type.

is that all it comes down to, is validation? ive heard things like dont use a numeric field unless you are going to do calculations, because its faster for a printer to print from a text field then a numeric. but on the other hand a numeric field will take up less space. etc...
any comments in that respect? or is space and speed not that big of an issue anymore?

If your database is small to medium size, then "speed and space not that big issue anymore" considering the technology nowadays: anyboday can get a very speedy PC for a cheap price.

What I think it all comes down to, according to a programmer's perspective, is the ease of programming and hencetofore maintenance. You get it to work first with my above comments.
