It say OnOpenPage is not a valid trigger and i cant get any other trigger to come up in intellisense, as well as typing them manually continues to say they're not valid triggers.

here is the error.

"Documents\AL\ALProject2\Date Type Card.Page.al(27,25): error AL0162: 'OnOpenPage' is not a valid trigger"

Ive tried reinstalling the AL extension, renaming the file, and a few more things i can't remember, this makes 0 sense as these as this is a valid trigger and every other page extension trigger does not work. Please help before I jump out a window.

Sure triggers are working, it's just in the wrong place. You have it inside an action, page level triggers go outside all layout elements. Intellisense will tell you what is available from where your cursor is. Just type 'trigger' and then type 'on' and it should drop down a list of available triggers.

here's what shows up as available outside layout elements:


This is what's available in an action

OnOpenPage is not a valid trigger in an action

Thank you so much, really appreciate the detailed response, doing this course from Microsoft and it's not exactly the best at teaching specifics, again really appreciate your help!

Try this one:

There's a playlist with more than 20 hours of content
https://www.youtube.com/embed/videoseries?list=PL1FESh9FqyhQxkZXYYp1X1tTpXf3-9iSR

The videos are out of order in the playlist, there's a part 1 and part 2 for doing development in AL. I don't know who the dude in the first video is, kind of annoying how someone else's face is on 20 hours of dev training that I recorded

Haha i can imagine, I will definitely take a look at these, and appreciate the help!
