I have a calculation that I want to return as red, but I receive an error. I thought the syntax is correct, but I guess not. What am I missing?
<font color="red">int(${ValidX}) + int(${ValidY})</font>
Take a look at this post. I would do a second field as this show otherwise that html will be in your data forever.
I am also not sure you can use int since it is a string you are trying to make. Leave it or convert to string actually.
If you want it right by the question check out my post on using emojis. https://community.esri.com/t5/arcgis-survey123-documents/how-to-simulate-instant-data-checking-using...
Hope that helps
