Enabling add-in causes excel to crash
 

I am using Excel 2007...and saving everything as Office Excel 97-2003
Worksheet. I created an Excel 97-2003 Add-in called CompFxnsAddIn.xla
which contains the code at the bottom of this post.

The code seems to work fine...giving me the expected values, etc (they
are intended to be used on a timeseries in a single column). Anyway,
now everytime I open the file, I get the following notification:
"Excel experienced a serious problem with the CompFxnsAddIn add-in. If
you have seen this message mutiple times you should disable this add-
in and check to see if an update is available. Do you want to disable
this add-in?"

If I click no, Excel crashes. If I click yes, Excel loads. But then
when I go into Excel options/Add-Ins and check the compfxnsaddin box,
Excel crashes.

The only way I was able to get it to load was to enable/install Solver
Add-In and then afterwards it allowed me to enable my add-in.
However, next time I opened the file even disabling and re-enabling
Solver Add-In failed to work. I had to load something else new
(Conditional Sum Wizard) at the same time. Obviously I'm going to run
out of new add-ins to load very soon, but I don't understand what is
happening. I don't believe it has anything to do with the VBA
code....but I posted it just in case.

I was unable to google any other mention of something that seemed
relevant to this....but I am quickly getting fed up with the 20 minute
delays each time I want to get in the file.

Any help???? Please.....

Oh....and I'm running Windows XP.

Enabling add-in causes excel to crash
 

Hello 3,

Not having Excel 2007 I can't why you're having this problem, but here
a few things to keep in mind. When you create an add-in you need to have
code that will handle any possible errors. Case in point, if the user
passes rowsback and it it is greater the number of rows to the active
cell, you will get an error and everything grinds to halt. The other
problem here that can cause an error is rowsback is typed as an integer.
Rows should always be typed as long, unless you are sure you will never
exceed the integer limit.

Sincerely,
Leith Ross

I don't believe it has anything to do with the VBA code

I agree. If that is truly all there is to this add-in I think I try
recreating it from scratch. It may be corrupted.
