Error on calling OnBarUpdate

[AdeptistJune]

I get this error message when I try to use prints:

Error on calling "OnBarUpdate" method on bar 482: Index (zero based) must be greater than or equal to zero and than the size of the argument list.

What does this mean?

Thanks.

Hello AdeptistJune,

Thanks for your post.

This error can be seen when using String.Format. You would need to ensure that you are supplying arguments to String.Format with {0} {1} {2} etc. For example, if you are printing out 2 values, you would need to reference {0} and {1} for two formatting arguments

Ultimately, you would need to debug the script to find the exact line of code that triggers the error in question.

Below is a link to a forum post that demonstrates using prints to understand behavior.

I figured it out last night.
