Worksheet Code to react to column change

Hi all,

I'm trying to write a worksheet code that will run a macro when a certain value is selected in column H. Breakdown is...

I have 3 macros each called Daily, Weekly, and OneFee.
In column H of my worksheet (on several rows) I have a drop-down menu (data validation drop-down) that allows you to select "Weekly", "Daily", "One Fee".
What I want my worksheet code to do is run the relevant macro every time the user selects an option from that drop down menu in column H. I managed to do this when the target was just one cell, but I can't seem to figure out how to do it when the target is the whole of column H.

Any ideas?

Many thanks
