I have posted this before and didn't really explain myself at all well...so here goes.

I've tried various ways of doing this, still without luck, any suggestions would be cool.

I've got a project where upon I would like to specify the current tax week based on a text box containing a date.

For instance:-

My Text Box "txtTaxYearStart" contains a date manually entered by a user, which is the date their company starts their tax year.

Now from "txtTaxYearStart" I would like to be able to work out the current tax week.

If there are ways to do this I would be extremely grateful if you could share them with me.

A pre-empted enourmous thanks are due.
