Hi,

would like some help on running a macro with situational requirement.
e.g. cell B1 is list validated, and if scroll down and choose value "1",
it
automatically runs a specified macro to create other validation setting on
a
range of cells. if value "B", run marco B. its sth similar as a Button.

How do u think I can get this implemented?
pls help!

thx lots!
