Get value of an Anchor-Point of an Layer which name is choosen by CSV
Hello, have an Problem with my code. I have csv table with two columns: One “MarkerNr” and one “Landkreis” (german word for counties). I have a Slider with the rounded values of 1-10 which use to select the row i want to access. In the column “Landkreis”, i have the name of the counties (for example “Ortenaukreis”) and i have many Layer with the counties name (so for example one of the Layer names is “Ortenaukreis”, too). Now i want the Position of an Null Object too get set to the Anchor-Point of the choosen Layer Name from the CSV. But it doesn’t work, it will show an error message tranlated from german says something like: Layer-Index 0 not within the allowed range…
Here is my code:
markerNr = thisComp.layer(“Werte_Speicher”).effect(“Auswahl-MarkerNr”)(1); //this is the slider to choose the row
landkreis = footage(“Landkreisauswahl.csv”).dataValue([1,markerNr]); //get value from the csv at position of slider
l = thisComp.layer(landkreis); // acces the Layer with name written in the csv (e.g. layer with name “Berlin” or “Ortenaukreis”)
l.toComp(l.anchorPoint); // get position of the selected layers anchor Point in this comp
my CSV looks like the one in the photo i attached. Hope i could explain may problem good enough (my english isn’t the best) and someone can help me with this.

i found a solution that (kind of) works BUT still shows an error (while working). I think the problem is with the String which i use to access the layer. So i tried to convert it to a String but maybe i did it wrong or it is not the problem. With adding four ‘ to the code, it seems to kind of work.
The same when i enter the Layer-Name manually e.g.: l = thisComp.layer(“Berlin”);
–> this works fine too.
Here is the code that kind of works now:
markerNr = thisComp.layer(“Werte_Speicher”).effect(“Auswahl-MarkerNr”)(1);
landkreis = footage(“Landkreisauswahl.csv”).dataValue([1,markerNr]);
l = thisComp.layer('' +landkreis +''); //<<--- here i added ''
l.toComp(l.anchorPoint);But since it still shows an error i think there is something i am missing and i think it is they way it uses the String that i get from CSV… Hope someone can help me more

Try making a text layer and setting the source text using the expression to test what value landkreis is returning. E.g., put this on the source text property:
markerNr = thisComp.layer(“Werte_Speicher”).effect(“Auswahl-MarkerNr”)(1);
landkreis = footage(“Landkreisauswahl.csv”).dataValue([1,markerNr]);
landkreisThat will tell you if the data is coming from the csv properly

Did this already and works fine. No problem there – this is what bugs me. I can use it to get the text as source text and it always shows the correct string but as a Layer-Name it has problems… I think this really comes from the fact that you use “” for getting the Layer-Name. In my before post you can see i found a work around, the expression still shows error codes BUT it is working – don’t ask me why. Still hoping to find a proper solution that works without error…

Ok i found the solution… had to change variables value to a string:
markerNr = thisComp.layer(“Werte_Speicher”).effect(“Auswahl-MarkerNr”)(1);
landkreis = String(footage(“Landkreisauswahl.csv”).dataValue([1,markerNr]));
l = thisComp.layer(landkreis);
l.toComp(l.anchorPoint);this seems to work…
