Instructions said to make a new post when I went to add more help I needed on a thread.

I am trying to get a string location from a dictionary to be set as the value for a tag.  
I attempted the following in the tag scripting.

```auto
temp = system.tag.readBlocking(["[.]../../Equipment_State"])[0]
	
temp2=machine1.get_errorlocation(temp) 	
	
system.tag.writeBlocking(["[.]Machine1 Error Location"],[temp2])

```

I am able to write the correct equipment state to the tag using this code below.  
I verified this code works:

```auto
temp = system.tag.readBlocking(["[.]../../Equipment_State"])[0]
system.tag.writeBlocking(["[.]Machine1 Error Location"],[temp])

```

I verified in a binding script that the below code works in the binding section of an object on perspective

```auto
value=machine1.get_errorlocation(value) 
return value

```

For some reason though, I can’t get the value from the dictionary to become the value of the tag value.

for reference, here is what I had been working on

Your `temp` variable is not the tag value, but a qualified value object. Those are allowed when writing to tags, which is why your two-line action works. Pass `temp.value` to your lookup script.

Also take a look at the docs for readBlocking where it describes the return value.
