So with the help of the wonderful Adobe community I put together this script.

try { var newSpot = app.activeDocument.swatches.getByName("CutContour")}

catch (e) {

var newSpot = app.activeDocument.spots.add();

var newColor = new CMYKColor();

newColor.cyan = 0;

newColor.magenta = 100;

newColor.yellow = 0;

newColor.black = 0;

newSpot.name = "CutContour";

newSpot.colorType = ColorModel.SPOT;

newSpot.color = newColor;

var newSpotColor = new SpotColor();

newSpotColor = newSpot;

newSpotColor.tint = 100; 
 }

var _sel = app.activeDocument;
var spotColor = app.activeDocument.swatches.getByName('CutContour');
    _sel.stroked = true;
    _sel.layers[0].pathItems[2].strokeColor = spotColor.color; 
  

What i need help with is eclosing that last part in a for loop and replacing the 2 with a counter.

for (var i=0;i=<2;i++){
 _sel.stroked = true;
 _sel.layers[0].pathItems[i].strokeColor = spotColor.color;
}

 Like so. However this gives me the error that the compiler expected a { at line 3 in the above snipit.

can somone please tell me what I'm doing wrong. I'd greatly appreciate it.

Fixed it. Don't know why but I worked when I replaced "i" with "cnt" andcnt =< 2withcnt < _sel.layers[0].pathItems.length

i think the problem was in your for loop. in the loop condition, you have this:

 

i =< 2

 

instead of this:

 

i <= 2

 

edit for more clarification. As soon as the interpreter sees the "=" sign, it starts looking for a value to assign to the variable that came before it. in this case, your code is attempting to set the value of "i" to "<" which is invalid.

In order to check for less then or equal to, the less than must come first (likewise for >=, the equal sign needs to come at the end).

Yeah, that was my initial instinct too, but with both "<=" and "=<" I got the "expected {" error. Might have done somthing else wrong though.

there was nothing else wrong in the code you posted above.. i just tested this loop (which i copied and pasted from above, and flipped the >= to <=) and it worked just fine.

 

 

for (var i=0;i<=2;i++){
    //_sel.stroked = true;
    //_sel.layers[0].pathItems[i].strokeColor = spotColor.color;
    $.writeln("i = " + i);
}

 

 

edit.. it's possible you put a comma somewhere where there should have been a semicolon? like this:

for(var i=0;i<=2,i++)

i've done that loads of times and i think that would give you the same error.
