sinple calculation between sheets

[pccamara]

Hello

I'm having dificulties on doing some calculations between excel files. I have excel 2007 and all the other files are 2010. The gold here is simple: to get data from all files into that 2007 resume file. Can i do something about it?
One other thing, i'm working on a vpn network
Tks a lot

How about making a local copy of a file first? Can you do that? You could eliminate potential problems with VPN this way.
Normally, you shal have no (or rarely you could have - thre are some new functions in 2010) problems with 2010/2007 compatibility.
