Hello Everyone,
I have come here for some advice, im normally ok with Excel formulas but this has bambooozled me...
The formula works when i keep the date ranges between say for example 21.03.2017 and 31.03.2017
When i change the start date to 01.03.2017 and end date to 31.03.2017 it comes up with an invalid total.
It seems to be when i change the start and end dates to outside my criteria... (if that makes sense)
Ive attached the worksheet as an example could someone help me please.
