Hi there - this is an easy one I think but I can't seem to get it right!

Tab 1 contains a schedule listing items and quantities - there are multiple lines for each item.

I want to add the quantities from Tab 1 to a summary total for each item on tab 2.

I need this to be a formula so that if the quantities change on the Tab 1 schedule this is reflected in the summary on Tab 2.

I think this might be a SUMIF...but I can't get the range and criteria right...

Thanks

L
