OnPrint Function Error

[Pam]

Please forgive the repost of the same topic, but I really need to get a
table of content report and keep getting error msg "Type Mismatch" for the
OnPrint function. I have followed the instruction from the Ms Article for
creating a table of contents in both the Northwind db and my db. It works
perfectly in Northwind, but my report gives the error. My grouping header
is PartNumber - it is a text field containg both numbers and text. I've
checked the "description" field in the toc table and it is text set to the
same number of characters as partnumber. I've searched thru post and web
looking for answer to what I'm doing wrong.

If anyone has answer, please let me know how to solve this VERY frustrating
problem.

Thanks,
Pam

It's hard to tell without seeing the code you are using.

Note that I have never heard of an OnPrint function. There
is an OnPrint **property** associated with report sections.
Normally, the OnPrint property contains:
[Event Procedure]
which means the Print event **procedure** is declared as:
Sub <section name>_Print( . . . )

OTOH, it is possible to call a function directly from the
OnPrint property by using the syntax:
=somefunctionanme(argumentlist)
If this is what you have, that error message could mean that
you have a text string in an argument that the function
declared as a number type. Or, maybe the function itself is
using a variable inappropriately??

Marshall,

Thank you for the quick response. Sorry about using "function" in the
OnPrint error description. I've included the code I'm using. Hopefully,
you will be able to tell why this won't work for me.

Thanks again,
Pam

That looks good to me. Is there any chance that there might
be a record where the PartNumber field is Null? If so, try
using:

=UpdateToc(Nz([PartNumber], "Unknown Part", [Report])

Marsh,

There is a PartNumber for every record in the query backing this report. I
tried the code you provided but received error "The expression entered has a
function containing the wrong number of arguments."

Do you have any other suggestions? I just can't get anything to work with
this but using the same code and only changing the name of the header group,
it works in the Northwind sample db.

Thanks again for your help,
Pam

I was missing a )

=UpdateToc(Nz([PartNumber], "Unknown Part"), [Report])

But, from what you've posted, if it's not a Null part
number, I don't see where you would get a type mismatch
error. Are you sure it's not coming from some other code?
Have you stepped through the code or used nreak points to
isolate the line with the error.

Marsh,

I tried revised code, but you guessed - it still didn't work: Type
Mismatch. I went to the module and placed the cursor at the beginning line
of InitToc and selected Debug>Step Into and it highlighted the line yellow.
I went thru the remaining lines in this function and then Step Out. When I
tried to do the same for UpdateToc, it wouldn't highlight only a (blocked?)
type sound from computer. I'm sorry - I know this sounds strange to you,
but I've not worked with "stepping thru code" enough to know exactly what I
should be doing. I still don't understand if it is with the UpdateToc
coding why it works on the sample db.
Does this give you any clues as to what is wrong?

Try placing a break point on the first line in the UpdateToc
function (just clisk on the left margin of the line and it
will turn dark red when it's set). Then switch the report
to Preview and the code will stop when it hits the break
point. See what you can learn from stepping through from
there.
