I am having trouble with my expression not going true even though both conditions are right for it to be. The screenshots were taken at 1:27 but the tag is false right now. Any help would be appreciated!

I can see two possible problems.

First, the `&&` has a higher precedence than the `= False`, so your expression is evaluating incorrectly, I'm pretty sure.

Second, you don't have a poll rate on `now()`, so your expression isn't re-evaluating during downtime.

I would rewrite it like this:  
`!{IsAvailableTag} && minutesBetween({uptimeTag}, now(60000)) > 5`

Note that there's zero reason to include an `if(condition, True, False)` - you can just write your condition out, and it'll automatically return a boolean result (or be adapted to a boolean by whatever context is running the expression).

Thank you so much and I did not know that I the if statement was not needed. I appreciate it!

Tip: post formatted code instead of or as well as the screengrab so we can copy, test and edit it. Please see [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831). Also, you can break lines in expressions and use indentation to make them more readable. The interpreter ignores line breaks, tabs and multiple spaces.
