`IF(condition, 'true val', 'false val')` Conditional (if/else) Lets you return one of two values based on whether the given condition is true or false. Useful for toggling a field’s dynamic value based on previous answers. eg  IF({{score}} = 50, ‘YOU PASS’, ‘YOU FAIL’)
`ISBLANK(val)` Is Blank or Empty Returns true/false based on whether the given value is blank/empty. An easy way to check if a field has no answer.
`NOTBLANK(val)` NOT Blank or Empty Returns true/false based on whether the given value is not blank/empty. An easy way to check if a field has any answer.
`COALESCE(val1, val2)` First Non-Empty Value (coalesce) Use this function when you want to guarantee a non-blank value is returned. This is useful when doing scoring calculations – wrap each answer in a  COALESCE({{answer}}, 0)  to ensure you get a zero if the user has not provided an answer.
