Object reference not set to an instance of an object?

I have made this visual novel but there's this error that keeps appearing. "NullReferenceException: Object reference not set to an instance of an object" Usually, you can't run games with error but I can run it with this error and works like its suppose to. It works in exe too. However, it just does not work in WebGL which is the format I want it in. Please help! The code is below. PS: The error is in the displayImage and displayText code.

i'm pretty sure it's because webgl can't load resource from a local path

 

Huh? What does that mean? The other people could run theirs fine. Or do I not put the sprites in folder?

 

You say "It works like it's suppose to", but "it just does not work in WebGL" ... So, which is it?

If your error is with displayText and displayImage, but they appear to be working when you run them, you most likely have a duplicate of the script in your scene somewhere.

 

It works in the game tab for Unity and Exe. But it comes up with an error when run on WebGL.

 

Then again, make sure you don't have a duplicate script. Otherwise, look at your javascript console and see what it says. (which isn't always helpful, but sometimes)

I'll try. Thanks.
