Exists function with User Variables - is it possible?

[gdpodesta]

We want to conditionally prepend a disclaimer to a video, and to accomplish that, we generate a png file before the FFAStrans job begins.
The Insert Media works as expected, but I'm unable to get a simple conditional to recognize if the disclaimer file exists or not.
To test this and get it working, I've set up this workflow.

• Populate variables, mimicking the API submission of the job

• Test if the Disclaimer file exists or not

• If NOT found, write a text file "NOTFOUND.txt"

• If found, write a text file "FOUND.txt

i copied/pasted the conditional from the help text, and am certain the file does NOT exist, yet the only process that it continues on to is the result of a successful test - it never takes the failed test path. Is there something blatantly wrong with any of these nodes that I'm somehow missing?

Hello gdpodesta,

Very productive right now That's great!
Anyway, you forgot the quotes inside your exists function.
must be :
$exists("%s_disclamer_png%")

Try with quotes and it will be ok

Cheers.
