The ToolPac Add-in was exactly the problem. The tip on the formula
concatenation is also good to know. Always looking for ways to shorten the
formulas.

Thanks, Appreciated the help.

From Excel Help when I search for YEARFRAC: If this function is not
available, and returns the #NAME? error, install and load the Analysis
ToolPak add-in. Sounds like you have the ToolPac installed and the others do
not. Check Tools | Addins.

BTW: in the formula VLOOKUP(B1&+","&+C1,'Hire Dates'!$B$2:$C$949,2)
the + signs do nothing, you need only the concatenation operator &

I have following formulas in a worksheet, they work perfectly and provide
the
exact results I'm looking for. However, when another person opens this
file
on their PC, whether from the same network directory or from an e-mail
attachment, all the results from these formulas turn to #NAME?.

Need to find out why this happens and how to correct this issue.

cell B1 and C1 are the first and last name of an employee.
cell D1 is the employee's birthdate.

cell P1 has the following formula and the result should be the hire date
found in a table that is in a separate TAB in the same file:

VLOOKUP(B1&+","&+C1,'Hire Dates'!$B$2:$C$949,2)

cell Q1 has the following formula and the result should be the years and
months employed:

IF(P1="","",TEXT(TRUNC(YEARFRAC(D1,TODAY()),0),0)& +IF(TEXT(TRUNC(YEARFRAC(D1,TODAY()),0),0)=1,"
yr., "," yrs.,
")&+TEXT(TRUNC((YEARFRAC(D1,TODAY())-TRUNC(YEARFRAC(D1,TODAY()),0))*12,0),0)&+IF(TEXT(T RUNC((YEARFRAC(D1,TODAY())-TRUNC(YEARFRAC(D1,TODAY()),0))*12,0),0)=1,"
mo. "," mos."))

cell R1 has the following formulas and the results should be the years and
months of the person's age:

IF(P1="","",TEXT(TRUNC(YEARFRAC(D1,TODAY()),0),0)& +IF(TEXT(TRUNC(YEARFRAC(D1,TODAY()),0),0)=1,"
yr., "," yrs.,
")&+TEXT(TRUNC((YEARFRAC(D1,TODAY())-TRUNC(YEARFRAC(D1,TODAY()),0))*12,0),0)&+IF(TEXT(T RUNC((YEARFRAC(D1,TODAY())-TRUNC(YEARFRAC(D1,TODAY()),0))*12,0),0)=1,"
mo. "," mos."))

cell S1 has the following formula and the result should be true or false
as
to whether or not the employee has 5 years of service and is 55 years old.

IF(P48="","",AND(TRUNC(YEARFRAC(P48,TODAY()),0)5, TRUNC(YEARFRAC(D48,TODAY()),0)=55))
