Excel/Macro debug?


Hi Tom
I have started getting the following error messages when I open up my latest workbooks:
“excel run-time error 91 object variable or with block not set”
There are two issues here:
One this message shows up a particular function will disappear
There is no option to “debug” with this error.
Have you any suggestions as to how I might approach this problem?

Thanks in advance.
Chris Mitchell

Christopher Mitchell,

> One this message shows up a particular function will disappear

So which one?  what cell(s) are impacted?  "Particular function" doesn't really tell me anything.

I believe this error popped up with the workbook you sent me.  I will have to see if it repeats and if it does, then take a look at it and see if I see anything.    Knowing nothing about what code you have in the workbook or what it is doing, or what you might have been or had been doing when it appeared . . .   anyway, I will see what I can see.
