I am using a script on a button actionPerformed to submit change modifications to a change log. When I run it in the vision client launcher, I keep getting errors. Does anyone know a solution to this issue?

These are my versions of Ignition and Java:  
Ignition v8.1.7 (b2021060314)

Button Script:

One of these is `null` / `None`.

Most likely `revDate`, which value comes from a component.  
I can't imagine `system.date.now()` returning `None`.

So basically what I am trying to do is make my second script email out to my team. I am trying to edit this script which was previously written by another engineer and I am a little lost. This is the original script which writes to a table (the change log)

Now I keep getting the error that 'productionreq' is not defined but I put it into my named query and into the script so I dont understand why it says its not defined.

Current Script:

You have defined productionreq inside the scope of an `if` statement and then tried to use it outside of that scope.

I suspect that you will have the same issue with safetyreq, engineeringreq, and qualitynote.

Also, you should be using boolean built-ins instead of 1 or 0.

So this:

```auto
#conditions requiring production approval
if sop == 1 or recipe == 1 or parameter == 1 or physical == 1 or chem == 1 or automation == 1 or ocSafe == 1 or safetyBypass == 1:
	productionreq = 1
else:
	productionreq = 0

```

Should really be this:

```auto
productionreq = sop or recipe or parameter or physical or chem or automation or ocSafe or safetyBypass

```

The better, more pythonic way to write that is using the any() function.

```auto
productionreq = any((sop,recipe,parameter,physical,chem,automation,ocSafe,safetBypass))

```

Also, the original script has it written that way and works fine. I am not sure what the difference is here.

The only other thing I see is that ReqProduction is defined twice in the parameters dictionary in the call to runNamedQuery().

When I pasted this into the script console line 120 is a comment. What line is line 120?

Try commenting that out. It should really be at the end, anyway.

Also, throw in a few `print productionreq` lines in there. Ensure it is getting initialized and that no other oddities are happening.
