Create a simple formula
When creating a formula there are some things to consider:
The selected data source elements are always the ones you start with when entering the formula builder - so it is easy to spot the right datasource
You can either start with a function, they can be added after the data source as a suffix, for some, you can even use symbols such as +, -, /, *, =, ≠, >, <
If you want to add text to a formula field you need to put this text in quotation marks. For instance, a text would now look like this: "abc"
If you want to add a number to a formula field you can simply insert it without quotation marks
