Is it possible to use a global variable as the argument of the "footage" function?

Question

Hello,

I'm looking for a way how to use a global variable as the argument of the "footage" function. Not sure if it's possible at all.

It should be simple, but it doesn't work for some reason:

var path = eval(thisComp.layer("GlobalFileName").text.sourceText)
footage(path).dataValue([1,1,0,15]) + (" Frames")

In this version, I'm getting the "Couldn't find footage named 'Text Property' " error... So, it looks like the "footage" function can't read the "path" variable. Or probably can't use the variables at all?

But in this case, for example , it works just fine and I'm getting the proper text on the screen:

var path = eval(thisComp.layer("GlobalFileName").text.sourceText)

path

Any ideas how to fix that? Need that for parsing a lot of json files... just want to implement some automation.

Thank you,

Paul

it works this way -  path = thisComp.layer("Global_Text").text.sourceText.valuemyFootage = footage(path);footage(myFootage.name).dataValue([1,1,0,15]) + (" Frames")

Your code does not contain any proper string processing, so I'm not sure what you are hoping to do here. eval() simply returns an infinitely long unprocessed string that is treated as code that can be evaluated, but of course if it contains actual strings or URIs you have to isolate them from the rest and possibly account for operating system specific oddities like name handling, path delimiters and so on. You need to put in more effort and harden your code to make this work like adding toString() or decodeURI().
