First test:
On my first test, I’ve replicated your concern with simpler values:
‘<progress style=”accent-color:red;” value=”‘||55-5||'” max=”100″></progress>’
Results:
Which is to be expected based on your concern.
Second Test:
I followed your advise wherein if I change the arithmethic symbol to * or /:
‘<progress style=”accent-color:red;” value=”‘||10*5||'” max=”100″></progress>’
Results:
With this, it shows the correct progress bar as you’ve mentioned.
Final Test:
With this knowledge, I’ve added parenthesis ( ) to the arithmetic expression while using the minus symbol:
‘<progress style=”accent-color:red;” value=”‘||(60-5)||'” max=”100″></progress>’
Results:
With this final formula, I was able to display the correct progress bar whilst using the minus symbol.
