How to make multiple \footnotemark and \footnotetext match?

Question

As the title, I want to insert two pairs of \footnotemark and \footnotetext in the block environment, but the superscript number of the mark is different (e.g. 3 and 4), but the superscript number for the text is the same (e.g. 4).

Answer 1

In my comments, I showed ways to play with optional arguments to \footnotetext to fix the problem. I also showed ways to play with the footnote counter.

However, the real way to fix this is to issue the \footnotetext macros immediately after the corresponding \footnotemarks. This is because the invocation of \footnotemark steps the footnote counter. And that is the proper time to issue the \footnotetext invocation unless your environment precludes it.

Answer 2

The matter is that \footnotemark also increases its counter, so maintaining a private counter solves the problem:

% replace existing \footnotetext with \note
\newcounter{note}
\newcommand{\note}[1] {
    \stepcounter{note}
    \footnotetext[\arabic{note}]{#1}
}
