bad page number in footer and misc

Question

I've a number of problems with my scrletter:

• I need the page numbering on pg 1 to be in format "n of N" like the rest of the document (scrletter global option firstfoot=false does not resolve it)
• the appendix TOC does not generate with each item (\section{}) nor does it say "appendixes" instead of "contents".
• the my gantt chart nor the pdf attachment appear on the same page as the appendix identifier, but I don't want them to start on a new page.
• anything in the appendix breaks the breaks the page numbering from "n of N" to "N+1 of N".

Answer 1

• Use \setkomavar{firstfoot}{\raggedleft\pagemark}.
• A section with empty title does not get a ToC entry. Therefore replace \section{} by \section{~}. If the title of the ToC should be »Appendices« redefine \listoftocname: \renewcommand{\listoftocname}{Appendices}
• Use option pagecommand for the first included page to get the section heading on this page. Replace environment sidewaystable by sideways.
• The reason for the broken page numbering was the sidewaystable at the end of the letter.
