Revised formula required for a timing plan workbook

Could someone please help me to write a new formula. Currently I have this:

=SUMPRODUCT(('Timing Plan'!$V$8:$V$1032)*('Timing Plan'!$P$8:$P$1032=$C13)*('Timing Plan'!$H$8:$H$1032<BX$7)*('Timing Plan'!$I$8:$I$1032>=BX$7+1))

$V$8:$V$1032 = average required hours
$P$8:$P$1032=$C13 = Person responsible
$H$8:$H$1032<BX$7 = start date of task
!$I$8:$I$1032>=BX$7+1) = task deadline

This averages out the allocated hours to a ask from the start to end date. There is a column M that allows you to enter the hours completed to date. I would like the hours to readjust over the remaining days if for example more hours were consumed one week or if less hours were consumed another week.

Administrative Note:

We would very much like to help you with your query, however the thread title does not really convey what your request is about. Practically everybody here is hoping for help with a formula.

Please take a moment to amend your thread title. Make sure that the title properly explains your request. Your title should be explicit and not be generic (this includes function names used without an indication of what you are trying to achieve).

Please see Forum Rule #1 about proper thread titles and adjust accordingly. To edit the thread title, open the original post to edit and then click on Go Advanced (bottom right) to access the area where you can edit your title.

(Note: this change is not optional. No help to be offered until this moderation request has been fulfilled.)

That's better.

Will you please attach a small sample Excel workbook? We are not able to work with or manipulate a picture of one and nobody wants to have to recreate your data from scratch.

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired results are also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment, so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.

You can strip out confidential links from a copy of the sheet. We only need to see the relevant bits, anyway, not the whole she-bang.
