Thanks for your reply…got a solution from Dan Ebberts, saved me a whole bunch of time.

The Null was called Pic Contoller. It has 3 keyframes, wanted to change the second one from 123% to 98%

function fixScale(){

var myComp;

var myLayer;

var myProp;

for (var i = 1; i <= app.project.numItems; i++){

if (app.project.item(i) instanceof CompItem){

myComp = app.project.item(i);

for (var j= 1; j <= myComp.numLayers; j++){

myLayer = myComp.layer(j);

if (myLayer.name == “Pic Controller”){

myProp = myLayer.property(“Scale”);

if (myProp.numKeys > 1){

myProp.setValueAtKey(2,[98,98]);

}

break;

}

}

}

}

}

fixScale();
