I am currently trying to have an email sent if a tag reads in between certain values. I also want the email to contain the machine number that the tags are coming from. I have the machine number set as one of the parameters of the tags. This is the current code I am working with:

```python
if currentValue.value > 5 and currentValue.value < 10 or currentValue.value > 18 and currentValue.value < 20:
				
				body = '{ENumber}' + "had a yellow zone resul of:" + currentValue.value
				rec = ['ryan.craig@colder.com']
				
				system.net.sendEmail("smtp.dovercorporation.com", "BurstTesters@colder.com", "Burst Tester Caution", body, 0 , rec)

```

which is giving me this error:

([default]E398/E398/Test2BurstFinal, valueChanged) Error executing tag event script: Traceback (most recent call last): File "tagevent:valueChanged", line 26, in valueChanged TypeError: cannot concatenate 'str' and 'float' objects

I also tried this code:

```python

			if currentValue.value > 5 and currentValue.value < 10 or currentValue.value > 18 and currentValue.value < 20:
				
				body = str({ENumber}) + "had a yellow zone resul of:" + currentValue.value
				rec = ['ryan.craig@colder.com']
				
				system.net.sendEmail("smtp.dovercorporation.com", "BurstTesters@colder.com", "Burst Tester Caution", body, 0 , rec)
	

```

which is giving me this error:

([default]E398/E398/Test2BurstFinal, valueChanged) Error executing tag event script: Traceback (most recent call last): File "tagevent:valueChanged", line 26, in valueChanged NameError: global name 'E398' is not defined

Any idea how to fix this issue?

We have no way to know what line 26 is if you don't post at least 26 lines of your script 😄

But, it's pretty much guaranteed to be this line, or a similar one earlier:

```python
body = str({ENumber}) + "had a yellow zone resul of:" + currentValue.value

```

In **expressions** , you can just curly-braces to insert dynamic references to properties and tags. In **scripting** , you cannot - you are bound to the semantics of Python, because that's the language you're using.

So what you are _meaning_ to do, I assume, is read a sibling tag `ENumber`, but what you are _actually_ doing is trying to create a Python set literal with one member, the variable `ENumber`.... which (probably) doesn't exist in the local scope.

You need to use the `system.tag.readBlocking` function to read _any_ tag from scripting. The function returns a list of qualified value objects. So the most direct translation of this line would be something like this:

```python
qvs = system.tag.readBlocking(["[.]ENumber"])
ENumber = qvs[0].value
body = str(ENumber) + "had a yellow zone resul of:" + currentValue.value

```

Also, you need to cast `currentValue.value` as a str, because it's apparently a float (based on your conditional checks).

```python
body = str(ENumber) + "had a yellow zone result of:" + str(currentValue.value)

```

My mistake, yes the script I posted was line 26. This solution seemed to do the trick, thank you!

I noticed that, as well, after I made this post. Thanks for the help!
