Stacked column and Line Chart - Line data showing as the 'sum' total and not individuals values?

[Rose1976]

Hi, I have two data tables which contain two sets of 'source' data, plus a targets table and a date table.  I am trying to show a stacked column and line chart with the sales from one table and the sales from the second table as columns, and the targets (from the target table) as the line data.  However, the line data comes up as a single straight line showing the 'sum' of the targets rather than plotting the targets against the column information.

I believe its a relationship issue, but can't work out how to fix it. 

Can someone help me please?

Many thanks,

Rose

I am going to give this a stab.

Get rid of the two lines going to the Target table and connect the Date in the Target table to the Date table.
