rexexp help needed

[henry atting]

Hi,

I am trying to build a rexexp that does the following:
I have a text file where I want to replace

    Medicine:One:Two            €12.00

With 

    Medicine                    €12.00

Because I have more than one entry `Medicine' (and they 
differ slightly, something like `Medicine:Three:Four' and
so on) I have to do it with `quere-replace-regexp'.
With regexp-builder I found this:

    Medicine:.*[^€.0-9]

This works both in regexp-builder and a scratch buffer, but
unfortunately not in a file. If applied on a file replace-regexp
strips everything from the first `:'.


Kind regards
henry
