[moogeedoo]

Hello My Masters & Colleagues, I have 3 columns of data in sheet2 (A) for Branches (B) for Departments and (C) for Names A2:c5000 like the table below the 3 lists are related and has some duplicates and blanks. And I have 3 Columns lets say J,K,L in sheet1 I want to J2:J each cell is validation drop down list from sheet2 (A) without Dup. and blanks, then depending to your choice it's create the validation list from sheet2 (B), then depending to your choice it's create the last validation list from sheet2 (C). any one have a solution for this deadlock, kindly avoid array formulas it's take too much time because the size of data

For example:

Branch	Dept.	Name
Lima	Furniture & Interiors	Jackson
Lima	Food & Beverages	Emma
Jakarta	Real Estate Development	Olivia
Dhaka	Real Estate Development	Lucas
Lagos	Real Estate Development
Lagos	Fashion wear	Mia
Dhaka	Fashion wear	Caden
Karachi	Motor Vehicles	Jacob
Lagos	Shopping Malls	Logan
Lagos	Shopping Malls	Jayden
Lima	Furniture & Interiors	Madison

Thank you bro. for your kind support and quick reply, unfortunately the code has some issues the validation lists not changed when I change in the data in the sheet2 and when I change the sample data by my basic big data an error stop the code as shown in the attached Pic. I tried some changes in the code lines as much as my knowledge but unfortunately no avail.

when I open the file and select any cell it gives me Run time error 91: object variable or with block variable not set !!

I've just downloaded it and it did the same to me, try clearing the code break, close the file and reopen, that worked for me !!!
