Have you tried without .(dot)

Water tank distance at {{ Value }}
Could also be case sensitive. I see you have value with small v not capital.

It turns out that I cannot do this with a “Classic Condition” In order for it to work I needed to use a Reduce expression to reduce the sample set to a single value then use a Math expression to give a value of 0 or 1.

I can then use something like {{ $values.B.Value }} in the alert summary
