Formula not working

Hello,

I am quite confused with below formula I build:

=([Net Sales Value Euro]Where([Country Name]="GERMANY"))Where([Net Sales Value Euro]Between(5;9.9999))

when I divide the formula into two so:

=([Net Sales Value Euro]Where([Country Name]="GERMANY")

=([Net Sales Value Euro]Between(5;9.9999))

I have correct results when formula is split however when joined there are no results which is strange to me.

Can you please help me when I have made a mistake in the formula?

Thanks,

Tomasz
