Seriously, you should please follow the rules like all others too.
If you get any error message:

1. Post the whole error message so we can see the error message AND the line numbers AND the exapanded variables from the error mesasge
2. Post your code or at least the code block around the lines of the error message WITH line numbers or at least the line number where the error message hits

We cannot assume things nor do we like to and I personally often do not understand what you talk about in your posted code lines (what should "on editing the text field in the setting panel just below it." relate to in your posted code )

Many thanks for easing it for us all.

I also posted you the "how to read lua error messages" before already so maybe read the info there and learn to read the error messages, or ask questions about the error mesasges in detail so we can explain it to you better. You often, especially for nil errors, find out what's up if you understand the error messages and learn them, instead of ignoring them They tell you what is missing by the error text like "try to index a nil value" -> you got a table which is nil and try to access it somehow before it was created properly with = {}, etc.
