Hi and thankyou for your fast respons. I was not clear enough when writing
my
question. I will try to clarify:
When I open the worksheet I want the macro automatically to identify all
values in column F which are 4500 and colur those rows with yellow (if
the
macro not already have done it earlier). Mostly it will be only one row.
The
conditional format does what I wont but is only colouring the cell with
the
value. I want it extened to colour the whole row.

I may have misunderstood, formuultiple columns select the topmost row
(say
row 1) and drag down on the row numbers to select multiple columns then
proceed as in my other reply but modify the formula to

=$F14500
