After Effects Script – loop through selected items

[Avinash Ramanath]

I’m getting this Error Dan. Please help.

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

{
if (app.project.item(i).selected)
mySelectedItems[mySelectedItems.length] = app.project.item(i);
}
for (var i = 0; i < mySelectedItems.length; i++)
{

if (mySelectedItems[i].isStill){
var myComp = app.project.items.addComp(mySelection.name, 1920, 1080, 1, 4, 24);
}else{
var myComp = app.project.items.addComp(mySelection.name, 1920, 1080, 1, mySelection.duration, 24);
}

var myLayer = myComp.layers.add(mySelection);
}

What error are you getting? Also, if you’re going to post code, please don’t preview your post because it messes the code up.

Unable to execute script at line 12. After Effect error: Unable to call “addComp” because of parameter 1. Value is undefined.

It looks like you left out the code that defines mySelection.
