Because my Beamer files are large, I split then into separate
.tex files and start a new part with e.g.
This works in that the first section in this
.tex file correctly appears as Section 4 (correct also in footlines and headers).
However, in the TOC on the first page of the PDF, the first section appears as section 1, not as section 4! Same with the sections that follow: they appear as 2 and 3 in TOC, not as 5 and 6.
Is there a separate counter for the TOC? If so, how can I manipulte it?
