Only unique values to a combobox from multiple columns, vba

[einheri]

Is there a way to collect unique values from several columns (eg E4 to H1500) and put those values into a userform Combobox with no duplicates.

like: E4 F4 G4 H4
row1 Byan PDIV RSI2

Row2 E5 F5 G5 H5
RSI Byan T8 RS

and so on ......

Hope you understand
Thanks
