HI
In column A I have a row of figures.
In column B , I am entering figures which must be equal to or lower than
those shown in column A , comparing cell-for-cell A1 to B1 , A2 to B2
and so on.
What I need to do is to have a Stop message box pop up when the figure
entered in B is larger then the figure showing in A , asking that the
number be re-entered.
Can someone help?
Thanks.
