Hi,
Sorry for this basic question but...
How can I reference a function defined in a .xla file, from other vba
function defined in a .xls document?
I opened my Visual Basic windows. In the Project pane I see both the .xla
and the .xls files. But I can't call from the .xls Module1 no functions on
..xla Module1...

I have wide experience in Visual Basic but I can't get used to the way
objects are referenced in Excel. Where can I find information about it on
the web?

Thanks in advance
Faustino
