Power Query custom column based on two criterion

Hi there

I'm learning alot about Power Query :-)

I have solved this little problem.  I'll share my result in case it helps others:

My Timesheets query custom column calls the function:  fnLookupNameDateMatch([Name],[Date],"Team",#"Staff Movements")

The function is thus:

/*  Filter the lookup_table by lookup_name and lookup_date, and return the value in the specified column*/
(lookup_name as text, lookup_date as date, return_column as text, lookup_table as table) as any =>
let
        FilterTable = Table.SelectRows(lookup_table, each Text.Contains([Name], lookup_name) and [Joined] <= lookup_date),
        ReturnResult = Record.Field(Table.First(Table.Sort(FilterTable,{"Joined",Order.Descending})), return_column)
in ReturnResult

Thanks to all for reading and replying.
