[SOLVED!]  
Hello,

I’m not sure if these are bugs or if the way I’m using the code blocks is not right.

[UPDATE: Fixed via adding an after block from comment below]

1. I cannot restart the countdown timer within the “on countdown end” block.

[UPDATE: fixed by changing the variable “day” to “myDay” since I guess this was due to the built-in/default JS variable of the same name]  
2. As a result of the above blocks, it also looks like the “change variable by X” block is not working as expected? When I call the splash with the day variable passed in it, the program doesn’t run. I get the “oops, please check your code for errors” message, and when I look in the JS it looks like this:

You cannot reschedule the countdown timer right after it ends. You must wait a bit.

I will try to find a particular extension that helps with this…

EDIT: You must use a `after x do` block in the awesome timers extension by Daryl. Original forum post link [here](https://forum.makecode.com/t/timers-extension-after-x-debounce-throttle-and-in-background/1925)

Here is the Github link:

Thanks for the quick response! 😃 That works.  
I also commented that I was inadvertently trying to write to a pre-existing default JS “day” variable.

re: starting a new countdown in an `on countdown end`, that’s a bug that’s been fixed in the next release (/ is fixed in beta), but yes, for now you have to run it separately.
