Location Oriented Formula

[Loadmaster]

In cell E4 I have the formula:
=IF(ROUNDUP(MONTH(D4)/3,0)=ROUNDUP(MONTH(TODAY())/3,0),EDATE(DATE(YEAR(TODAY()),3*ROUNDUP(MONTH(TODAY())/3,0)+1,1),3)-1,DATE(YEAR(TODAY()),3*ROUNDUP(MONTH(TODAY())/3,0)+1,1)-1)

E4 also has two conditional formats:
Condition 1 is Formula is =IU4=FALSE
To format shading as White

Condition 2 is Formula is =IU4=TRUE
To format shading as Red

In cell IU4 I have the formula
=OR(AND(TODAY()=DATE(YEAR(TODAY()),INDEX({3;6;9;12},INT((MONTH(TODAY())+2)/3))+1,0),D4<DATE(YEAR(TODAY()),INDEX({3;6;9;12},INT((MONTH(TODAY())+2)/3))-2,1)),D4<DATE(YEAR(TODAY()),INDEX({3;6;9;12},INT((MONTH(TODAY())+2)/3))-5,1))

Cell IU4 has no conditional formatting

When I enter the 25 Mar 09 in cell D4 cell E4 reads 30 Sep 09 with red
shading, like it should. When I enter 25 May 09 in cell D4 cell E4 reads 30
Sep 09 with white shading, like it should. When I enter 25 Aug 09 in cell D4
cell E4 reads 31 Dec 09 with white shading, like it should.

However, at work with the same formula in cell E4 on my memory stick the
formula shows up in the formula bar as:
=IF(ROUNDUP(MONTH(D4)/3,0)=ROUNDUP(MONTH(TODAY())/3,0),'C:\Program
Files\Microsoft
Office\OFFICE11\LIBRARY\Analysis\ATPVBAEN.XLA'!EDATE(DATE(YEAR(TODAY()),3*ROUNDUP(MONTH(TODAY())/3,0)+1,1),3)-1,DATE(YEAR(TODAY()),3*ROUNDUP(MONTH(TODAY())/3,0)+1,1)-1)

With #NAME? in cell E4.

How can I get this formula to display at work the way it shows up in my
hotel room?

Have you installed the Analysis tool pack on your work PC?

Hope this helps.
