1st I declare the 2 datasets  
2nd I get all the paths in tagDS  
3rd I try to get the values but it is when the error appears  
it gives me the error at line 9 but i can not see how to fix this, thank you.

I think the thing that’s getting you is `tagDS[tag]`. In the loop `for tag in tags:`, `tag` is not a number it’s an object. What version of Ignition are you using.? You can use system.tag.readBlocking() or system.tag.readAsync() to read many items at a time, so this looping may not be necessary.

by the way; how is that about the readblocking to avoid the loop? could you be so kind to explain to me? i have read in the documentation that functions but i tought it would be the same
