Hi - I hope someone can help with a formula problem- with 3 columns
covering
dates/ date ranges and using another for a % complete figure

I have 1 column with a range of week dates covering 6 mths ( Col A)
I have 1 column with lots of dates ( Col B) and another with a % complete
figure ( Col C) against the dates

what i would like to do is a "count if" ( or something similar - help) for
