maybe you're in protected mode

% assumes \protect earlier

\unprotect
\def\autopuncttest#1#2{%
   \removeunwantedspaces%
   \doifinstring{#2}{,.!?;:}{#2}%
   \footnote{#1}%
   \doifnotinstring{#2}{,.!?;:}{#2}%
}
\protect

% assumes \unprotect later

or something

\pushcatcodetable \setcatcodetable\ctxcatcodes

\def\autopuncttest#1#2{%
   \removeunwantedspaces%
   \doifinstring{#2}{,.!?;:}{#2}%
   \footnote{#1}%
   \doifnotinstring{#2}{,.!?;:}{#2}%
}

\popcatcodetable
