It should look like this:

if (playerchats) {
if (!voted) {
if (strequals(#c,vote yes)) {
setstring server.voteyes,#v(strtofloat(#s(server.voteyes))+1 );
set voted;
}
if (strequals(#c,vote no)) {
setstring server.voteno,#v(strtofloat(#s(server.voteno))+1);
set voted;
}
}
if (strequals(#c,show results))
message Yes - #s(server.voteyes), No - #s(server.voteno);
}

The hardest part is probably the setstring thing,
but it is needed to store the result as a
server flag.
