I need macro that would enter certain text value in specified cells if
certain value is entered in another cell.

For example i have following worksheet

A B C D
1 Biz xxx yyy zzz
2
3

I need macro that would enter "-" in column B and C if value "Priv" is
entered in column A (I select values from dropdown that is specified for
column A).
Macro should trigger when i select value "Priv" from column A cell.

In this case if i would select cell A2 and then choose value "Priv" then
value "-"should automaticaly be inserted in cell B2 and cell C2 and cursor
should stop on cell D2 (the active cell after macro runs should be D column
cell)

This should be applied for all cells in columns A,B,C,D

Any ideas ?
