thank you daniele, you were right, your suggestion needed a minor tweak that incorporated, works great

It works even without the added parentheses

This doesn't give a correct result if the day of the week input is a Sunday. It returns the Monday after, not the Monday before.

If you alter the function to this:
input - DayOfWeek ( input -1 ) + 1
then it gives the previous Monday when a Sunday is specified.

It may be that some people want to calculate it as Darrin specifies, but I was caught out by the Sunday date so thought it best recorded here. Thanks for a useful function though
