id suggest to just play around with it, tie it to an obviously visible trigger, something along the lines of if 5 is pressed on keyboard a giant red box shows up, or it sets a txt to something, from there you should be able to tweak things to see where the issue is, granted you probably did that before posting. i would also suggest to look for any other "every tick" events, maybe you have multiple which are in turn cancelling eachother out? or maybe two triggers to the same event. theres been a lot of times where it was just a matter of overlooking something, such as duplicates of triggers etc. also make sure the event isnt inverted, or set up with a special condition. worst case scenario, try remaking the event. if every tick doesnt seem to work try every 0.0001 seconds or something to that extent
