Parameter name: source

I receive this error and IDK why.

Error on calling 'OnBarUpdate' method on bar 4026: Value cannot be null. Parameter name: source

Could you help me?

Already fixed!

Hello 7robert,

Glad you were able to get the item fixed.

Was this a line in the code that was corrected?

(The error sounds like a variable named source had a null value)

Hi 7robert, do you mind sharing how you fixed it? Everything was working for me, and then I started getting this error, and I haven't figured it out yet. Thanks!

Nathan.

I found my error as well. I was calling an array I had not assigned any values to.
