Symbols Column not Displaying Symbols per Formula
I have this JOIN statement that works but it does not show the symbols setup for that column. Any idea why? Your help is appreciated in advance!
=JOIN([Previous Week Trend]27 + " " + [Previous Week Trend]30)
returns
Unchanged Unchanged

To get the symbols to populate, it has to be an output that matches exactly one of the symbol options.
In this case "Unchanged" is the text value that will output the yellow minus. It does this because "Unchanged" is one of the specified options.
"Unchanged Unchanged" is not a valid value for that type of symbol column and therefore is output as text.

@Paul Newcome Thank you for this. So, is it fair to say we cannot join symbols together in a symbols column as that column can only interpret one symbol at a time, else text, yes?

That is correct.
You could replace the "Unchanged" with hyphens and then use conditional formatting to make them bold and yellow.
=SUBSTITUTE(JOIN([Previous Week Trend]27 + " " + [Previous Week Trend]30), "Unchanged", "  ")
