How do I do If I want to show what weeks that occur between two dates?

s=selDay should be s=selDate

Hi!, I have pasted this into the custom function edit box. When I try to save it says ' the parameter cannot be found' and the selDay is highlighted What are the parameters I should specify? Is there anything else I have to configure ? Thanks

Wow, this is exactly what I was looking for to create a calc field. I just want to understand the math behind it all. Why start with 9 and subtract the day of the week, etc? Thanks for your work!
