Hi All,

In the attached file,

Given:
1) In 'Sheet1" my data are in Column A,B,C,D,E,F&G. On the userform, there are 4 'ComboBoxes' and 1 'ListBox'.

Required: As Userform activates, I want to
1) Populate whole data from 'Sheet1' in the 'ListBox1".
2) Populate 'Column A' data in 'ComobBox1'

Then,
3) Based on 'ComboBox1' selection populate matching 'Column B' data in 'ComboBox2".( Also, update 'ListBox1')
3) Based on 'ComboBox1' and 'ComboBox2' selections populate matching 'Column C' data in 'ComboBox3"".( Also, update 'ListBox1')
4) And finally based on 'ComboBox 1, 2 & 3", populate 'ComboBox4' from 'Col D' also update 'listbox1'

I used the code from above link, but unfortunately it did not work.

Please help me ! I have attached the file.

Thanks
