Cell will not update

[nitrofueled]

Cell "D3" has a drop down list of names that are linked to specific number
values on another sheet. These number values are named "four, five, six, and
eight" individually. I have written the following function in cell "D5."
{=IF(D3=four,"4",IF(D3=five,"5",IF(D3=six,"6",IF(D3=eight,"8","N/A"))))}
The function works initially, but if I change the name in cell "D3" cell
"D5" does not update and just keeps my value if incorrect condition (N/A).
How can I get the function to update if the name in "D5" changes? Thanks for
any help...

Your formula is wrong.
It quotation marks need to go around the text, not the numbers (unless you
specifically are wanting numbers displayed as text). Also, there's not reason
for the formula to be an array.
=IF(D3="four",4,IF(D3="five",5,IF(D3="six",6,IF(D3="eight",8,"N/A"))))

Note that if you actually need the #N/A error:
=IF(D3="four",4,IF(D3="five",5,IF(D3="six",6,IF(D3="eight",8,NA()))))

The text (four, five, six, and eight) are names for series of values that are
located on a seperate sheet. The number is what I want to be displayed when
a certain value is located within the specific series. So, if a,b, and c are
located in the series named "four" and I input "a" into cell "D3" I want cell
"D5" to display the number 4. Thanks for your help
