# [texhax] Summary: Incompatible list can't be unboxed

```Dear All,

I've just subscribed to the texhax list (as a matter of fact, just because
I had this problem), and I'm very glad I did so.  Several people wrote to
me personally, giving me the guidelines to finding out what my problem may
originate from.  Let me summarize those answers (I don't know if this is a
common usage here).  Also, I hope it is OK to mention the people who
helped me.

The problem seems to be (as in many other cases in TeX, as in many
programming languages, too) that the error messages do not always stem
from where the problem lies.  You can easily get messages like
"Incompatible list can't be unhboxed" (which originally means: don't try
to \unhbox a vertical box or vice versa) or "Missing endgroup inserted" or
"Missing } inserted" when

*your table/float/box is too large to fit on a page.*

This is actually what happened to me.  It has happened to others, but few
have written about it on the net: if you Google the error message, you get
this reference:

I thank Yuri Robbers for the most detailed reply, but also Hartmut Henkel
