Macro won't run macro
 

I have a macro that converts data from another Excel application. This
(conversion) macro uses a series of filters and "vlookup" combinations to
provide me with data in a format Ican use.

I then transfer that data to the target application by using a (copy) macro
to copy the data across.

When I try to combine the two macros in a third macro it simply refuses to
do anything after running the (conversion) macro.

However when I call up the (copy) macro manually it works perfectly well.

Any ideas?

Thanks
