Almost there!

And what about the decimals?

The numbers between 1 and 2?

Like this, I guess:

m = marker;
n = 0;
if (m.numKeys > 0){
  n = m.nearestKey(time).index;
  if (time < m.key(n).time) n--;
}
if (n > 0 && n <m.numKeys){
  linear(time,m.key(n).time,m.key(n+1).time,n,n+1);
}else{
  n;
}

I would go with something like this:

m1 = thisComp.layer("Shape Layer 1").marker.key(1).time;
m2 = thisComp.layer("Shape Layer 1").marker.key(2).time;

linear(time, m1, m2, m1, m2 - m1);

It's not clear to me what you're asking exactly, but maybe something like this:

m = marker;
t = 0;
if (m.numKeys > 0){
  n = m.nearestKey(time).index;
  if (time < m.key(n).time) n--;
  if (n > 0){
    t = time - m.key(n).time;
  }
}
t

Thank you for your reply Dan, and yes, i wasnt clear with my question.

The expression, is ok.

The counter started at the first marker, but they count comp seconds between markers and restarted at the second marker.

I wish the slider count first marker as 1 and second as 2 and subsequently.

Ah, OK. That's simpler:

m = marker;
n = 0;
if (m.numKeys > 0){
  n = m.nearestKey(time).index;
  if (time < m.key(n).time) n--;
}
n
