I found the problem, so I thought I would close the loop.

The problem was that in Auto_Open routine had a call to the .HLP file...
however the name of the file was typed incorrectly -- and I think was not
caught in the error trapping. This "error" resulted in the UDFs not
recognized when called from an Excel SS.

Needle in the haystack.

Sounds like a 'scope' thing where Excel is getting confused. Since changing

Nice work and have a great weekend!

Thanks... I've figured out where the problem is but now I need help fixing it.

The code I'm using includes functions I wrote in addition to functions that
were written by a previous co-worker. The co-worker went to the trouble of
creating a help file for some of his functions. The functions included in
the help file are the functions that aren't working (my functions and his
other "undocumented" functions work fine).

I can make any function work by changing the name of the function (so that
it isn't linked to the help file). For example, one of the functions is
called "TaxRate" -- if I change the function name to "aTaxRate" it works
fine.

Do you know what the issue might be?

Besides what Niek has said, you may be calling your UDF an 'illegal' name
that Excel is already using. For example, creating a udf called 'TEXT' or
'FORMAT' or 'VLOOKUP' (i.e. reserved words) is not a good thing and will
bring unexpected results.

I have an custom add-in that has a number of subroutines and UDFs. The
subroutines seem to run fine, but some UDFs are returning #VALUE.

At first I thought it was an error in the program so I set a break point on
the first line of code in the function to determine what the error might
be... however the code isn't making it there.

If I change the name of the function by adding an "a" to the front it works
fine.

Please help -- I have no idea where the conflict is.

Thanks in advance,
