How to copy and link 2 new documents with Vlookup?

Hey,

I have the following problem: I have made 2 documents that are linked with Vlookup. The first one with all the variables we will call VAR1 and the other one with all the Vlookup formulas, we will call Lookup1.
I want to copy all the formulas from Lookup1 to a new file, lets say Lookup2, but then Lookup2 is still linked to VAR1 so I want to create a new document VAR2 and link automatically all formulas from Lookup2 to VAR2.
Can you help me out?

Regards

Are Lookup and Var in the same file?

Than you could just copy and paste the file and you're done.
