This is what I get when I open it in notepad. I couldn't attach the shader in here.

Apologies for somehow missing out on a simple detail, but you'll also need to add a Saturate node in order to ensure that the value range that is passed into the Opacity port stays within the 0-1 range that it expects:



I'm not sure why the sample I've sent didn't behave as it should've at that time, but this should solve the issue!

Please let me know if this helps.
