Blank fields not showing data--how?

[imported_unknown]

I have a field that I would like to display no data on a form if the previous reference field is not filled.

For example, I have a computation of a few fields in a row and if that figure is not entered, I get a "#N/A."

I'd like to know how to get those "#N/A"'s to completely disappear if I do not fill in any information in the preceding fields.

Thanks

Something like

If(ISBLANK(preceding_field),"",Value)

Thanks.

The problem is that the referred field is also "#N/A". So, I'm referencing a #N/A field and in the final block, I'd like to not display anything, not even a zero.

IF(ISNA(Preceding_field),"",Value)???
