I came from Airtable and I used to be able to use a formula and add text only if a field didn't contain anything (NULL). But I cannot seem to do it with Smartsuite. Below is an example of the formula:
CONCAT([Description], " ", IF([Repair Details] == "", "" , " Details - ", [Repair Details]))
So for the bold part, I am trying to check if the Repair Details are empty ("") and if they are then basically do nothing (""), else add the text " (Details - ", but the formula does not allow me to do this. What is the correct syntax to check if a field is empty?
