Question : Excel dependable Dropdowns

Excel issue (may be limitiation)...I tried to search for solutions but without any luck...I have attached the sample excel file for better understanding.

So, I need to set dropdown list for first 4 columns (Dependable dropdowns), my problem is if I select the region as west then I want only state, ID & code to be displayed for "West" region and if I select particular state then only related other filters should be displayed and update the data fields.

This is just a simple file, I am dealing with 5000+ rows and excel only is my option since this will be distributed. I tried looking up each row for particular value and check duplicates ect....but very slow and not the decent way to do it....

Any help would be greatly apprecaited.

Thank you.

Answer : Excel dependable Dropdowns

hitsdoshi1,

The code below is in the attached workbook. Make the selections from the dropdowns in the yellow cells and the totals will be shown below. The totals are produced using this sort of formula:

=SUMPRODUCT(($A$2:$A$10000=$J$1)*($B$2:$B$10000=$J$2)*($C$2:$C$10000=$M$1)*($D$2:$D$10000=$M$2)*$E$2:$E$10000)

Hope that helps

Patrick
