I'm not angry, as you see I went on to actually post a response to the new criteria..
That was intended more as a friendly FYI about best practices when posting in the forum.


Anyway..

Not sure I follow what you're after with the 10%..
10% is NOT more than £1.00, but it IS more than 0.

You're testing the formula for M2>0, but then you're asking about more than £1.00 ??
Can you clarify?
