Extract unique values from a table and list along a row

Hi,

I need some help with creating an excel formula that can do the following:

1. Extract unique values from a table column, on the condition that the value of another column in the table includes certain text. This text will be selected from a drop down menu which already exists. The table will vary in the number of rows it has as its constantly being updated.

2. Take these unique values and list them along a row of a new table.

For example in the attached spreadsheet, i want to return unique 'Products' from the source table in cells G9, H9, I9 and so on, only for the 'Advertiser' that appears in cell G6. I then want to use these unique products and the date, to return the associated costs in the newly created table.

This all needs to happen automatically as the source data will be constantly changing, and the output table will be used to automatically update charts which are part of a 'dashboard' summary. For that reason i dont think i can do this using conditional formatting.

I'd be really grateful for any help in solving this.

Thanks,
Colin
