select layer 1 or layer 2

[flieckster]

i'm super new to scripting and i'm wondering how i set up a script to select 'layer 1' or 'layer 2'. i get files back from vendors and i can't action them because sometimes the layer i need is named either layer 1 or layer 2.

after that i can run a normal PS action.

thanks!

What are the characteristics the affected Layers will definitely always have (name, number of Layers, which kind of Layers, positioned top-level or in Groups, total number, will there be other Layers that share those characteristics, …)?

Edit:
Does this help?
Code: Select all// get index of layer/s of specified name and select layers;
// 2014, use it at your own risk;
#target "photoshop-70.032"
