Drill down resulting on two charts.

Hi Experts

I want to Drill down the combination chart which should provide data to multiple charts. (where Data is different for the each charts.)

i tried to use Drill down(insertion) value as source to combo boxes and these combo boxes controls the data for charts.

For Eg: When user clicks on July column, it is getting displayed in combo box of next chart(Data insertion is used). but, this combo box doesn't control the Chart. (it usually does when a value is selected from the list of values).

Hence, i'm stuck here. I can't achieve the requirement by simply using Insertion options.

Please Help me with this.

Thanks in Advance
