I've gota simple script that should read on tag value and write it to another. Both tags are floats. When I exectute I get the following error:

Error writing to tag '[default]Node 6 Wells2/LIT\_Tank': Error\_TypeConversion("Cannot coerce value '[7.900000095367432]' into type: class java.lang.Float")

I don't understand where I am going wrong. 7.900000095367432 seems like a float to me.

Share the script. It looks like you're trying to write a _list_ of float values to the tag, not a scalar float value.

You are correct. I was fast and loose with some extra brackets. Thank you.
