Steve,

That is a little complex to follow, but a couple of things occur to me.

First, does the ControlBook name include the [...] characters.

Secondly, is ControlAll a range name or a name constant. If it is a range,
does it point to the other workbook, in other words is ControlBook and Date
and all the preceding stuff redundant? You could define it as a simple
constant like A1:M10 for instance.
