Hi,

i had a bunch of tag events occuring when the value changed. they were all working perfectly, and then all of a sudden none of the script is executing. I have no idea what happened, all of the code is correct, and i cannot find an error anywhere else. Has anyone had this happen before? or know anything that could help?

I’ve seen that sort of thing happen when someone edits a shared script and leaves a syntax error.

hmm, thats probably a good thing to keep in mind, but for this project we dont use any shared scripts…

Any diagnostic issues on the tag with the event script? Would have a gear with red dot by it.

No, no issues, it seems to be fine?

post your code on the event handler and there might be something causing it to not run
