What there are expressions in multiple comps?

The same applies to the brightness expressions.

BeautifulthisComp.layer("Flares Animation!").effect("Show/Hide Slider")("Slider")Meaningful Reveal = thisComp.layer("Flares Animation!").effect("Brightness Slider (Enter)")("Slider").valueAtTime (time - .96);
Conceal = thisComp.layer("Flares Animation!").effect("Brightness Slider (Exit)")("Slider");

if (thisComp.layer("Flares Animation!").effect("Slider Switch!")("Checkbox").value>0) {Reveal}
else {Conceal}PowerfulReveal = thisComp.layer("Flares Animation!").effect("Brightness Slider (Enter)")("Slider").valueAtTime (time - 2);
Conceal = thisComp.layer("Flares Animation!").effect("Brightness Slider (Exit)")("Slider");

if (thisComp.layer("Flares Animation!").effect("Slider Switch!")("Checkbox").value>0) {Reveal}
else {Conceal}MessageReveal = thisComp.layer("Flares Animation!").effect("Brightness Slider (Enter)")("Slider").valueAtTime (time - 2.75);
Conceal = thisComp.layer("Flares Animation!").effect("Brightness Slider (Exit)")("Slider");

if (thisComp.layer("Flares Animation!").effect("Slider Switch!")("Checkbox").value>0) {Reveal}
else {Conceal}

I cannot believe I figured it out! I will do my best to explain the idea behind the code, and then I’ll just give you the code for your specific situation. The secret to combining two sliders to one property is: Conditional Statement

The secret formula is the if/else statement and a checkbox control with two keyframes (on then off).
So, you need to have your sliders equal to a value. the value can be written as anything, a letter a word, a number. I wouldn’t use numbers because it might look confusing.

v = first slider;
z = second slider;

if (thisComp.layer(“LayerName”).effect(“CheckBoxName”)(“Checkbox”).value>0) {v}
else {z}

Now, for the other flares, since they’re in different positions (on the y-axis), but you can’t use the “temp =” and the “[temp, 812]” so you need to add the {value + [0,0]}. Oddly, for this situation, I found that I have to subtract 287 from the original number. I don’t know why. I had to play around with it until I got it in the right spot.

Okay, I don’t know if that made sense that way, so here is what it looks like.

Beautiful Enter = thisComp.layer("Flares Animation!").effect("Position Control (Enter)")("Point");
Exit = thisComp.layer("Flares Animation!").effect("Position Control (Exit)")("Point");

if (thisComp.layer("Flares Animation!").effect("Slider Switch!")("Checkbox").value>0) {Enter}
else {Exit}
Meaningful Enter = thisComp.layer("Flares Animation!").effect("Position Control (Enter)")("Point").valueAtTime (time - .6);
Exit = thisComp.layer("Flares Animation!").effect("Position Control (Exit)")("Point").valueAtTime (time - .32);

if (thisComp.layer("Flares Animation!").effect("Slider Switch!")("Checkbox").value>0) {Enter + [0, 525]}
else {Exit + [0, 525]}
Powerful Enter = thisComp.layer("Flares Animation!").effect("Position Control (Enter)")("Point").valueAtTime (time - 1.4);
Exit = thisComp.layer("Flares Animation!").effect("Position Control (Exit)")("Point").valueAtTime (time - .57);

if (thisComp.layer("Flares Animation!").effect("Slider Switch!")("Checkbox").value>0) {Enter + [0, 1001]}
else {Exit + [0, 1001]}
Message Enter = thisComp.layer("Flares Animation!").effect("Position Control (Enter)")("Point").valueAtTime (time - 1.65);
Exit = thisComp.layer("Flares Animation!").effect("Position Control (Exit)")("Point").valueAtTime (time - .8);

if (thisComp.layer("Flares Animation!").effect("Slider Switch!")("Checkbox").value>0) {Enter + [0,1513]}
else {Exit + [0, 1513]}

I really hope this helps.

I know you posted this like 8 years ago, I hope that by now you have found the solution but in case not, I figured it out. The secret to combining two sliders [or other expression controls] to one property is: Conditional Statement

The secret formula is the if/else statement and a checkbox control with two keyframes (on then off).
So, you need to have your sliders equal to a value. the value can be written as anything, a letter a word, a number. I wouldn’t use numbers because it might look confusing.

v = (pick whip to the first slider);
z = (pick whip to the second slider);

if (thisComp.layer(“LayerName”).effect(“CheckBoxName”)(“Checkbox”).value>0) {v}
else {z}

v = thisComp.layer("LayerName").effect("1stExpressionControlName")("Point");
z = thisComp.layer("LayerName").effect("2ndExpressionControlName")("Point");

if (thisComp.layer("LayerName").effect("CheckBoxName")("Checkbox").value>0) {v}
else {z}
