Expenses Tracking Formula

Good Morning.

i am putting together a very simple profit and loss spreadsheet. this shows total product sales and various tabs for different outgoings.

Only 2 people are involved in this (MP & PW)

For each tab of outgoings there is a column which shows who has purchased a particular item.

For example the tab Red Grape Juice shows that MP spent SR554 within February.

I would like, if possible, to capture the expenses incurred by each person in the "Expenses Owed" Tab and to automatically populate when an entry is made on any of the out goings tabs

Red Grape Juice
White Grape Juice
Jam
Pepsi-7up
Grapes
Yeast
Misc

the idea being that if there is an entry in any of the above tabs showing MP or PW within the purchased by column, the expenses tab will be populated within the relevant table.

Thank you all in advance for your help.
