if there’s a keyframe between these two markers…
How can I say:
“if there’s a text keyframe between two comp markers on either side of the current time, display the source of the keyframe (for the duration between them)
and if there is no keyframe, display nothing” ?
I know how to acknowledge the nearest markers before and after the current time, but I don’t know how to acknowledge if a keyframe exists in the time between them.

I think this works:
n = 0;
if (thisComp.marker.numKeys > 0){
n = thisComp.marker.nearestKey(time).index;
if (thisComp.marker.key(n).time > time){
n--;
}
}
txt = "";
if (n > 0 && n < thisComp.marker.numKeys){
if (thisProperty.numKeys > 0){
t0 = thisComp.marker.key(n).time;
t1 = thisComp.marker.key(n+1).time;
for (i = 1; i <= thisProperty.numKeys; i++){
t = thisProperty.key(i).time;
if (t0 < t && t < t1){
txt = thisProperty.valueAtTime(t);
break;
}
}
}
}

Holy cow. Seems to be working. I have the hardest time understanding For loops. I know when I need to use them, but they just don’t click.
Thanks, Dan. I’m doing my best to wrap my head around this one. Seems like after your error prevention code, it’s actually not too bad.
