I am trying to change a Memory tag using a button. The tag is a BOOL. I’ve used this code in an Event on the button:

tagPath = “[default]SORTER\_A\_CUSTOM/testing”  
values = [0]  
system.tag.writeAsync(tags, values)

Every example I’ve found uses a an indirect path to the same tag. Is it possible to update another tag using a button, not a toggle or a checkbox?

Try changing the first line like so:

```auto
tags = ["[default]SORTER_A_CUSTOM/testing"]

```

writeAsync() needs a list for both tag paths and values.

Ok, after looking closer… it helps to match variable names AND saving before click on the button in the browser! LOL. THX!
