lookup with mulitple hits, these hits to be summed up

Dear Experts

I got a column of unique article numbers on a Sheet called 'Summary'.

Column A     Column B
Article_No    Total Numbers of Units Sold
90-443           40 ('to be retrieved from Sheet 'Sales')
90-445             9
90-448            etc.
etc.

Another worksheet called 'Sales' lists these article numbers often several times with the corresponding units sold

Article_No     Units Sold
90-443               7
90-445               5
90-448               9
90-443             10
90-445              4
90-448             17
90-443              23
etc.

I now would like to make a lookup on Sheet 'Summary', i.e. a formula ...
... should lookup all the hits for a give article number on Sheet 'Sales' and ...
... then sum up the units sold and display them in Column B on Sheet 'Summary'

Is this possible using a formula? That would be great.

Help is much appreciated. Thank you very much in advance.

Regards, Andreas
