Examples of Issues that cause this error:

Empty Conditional Rules

1. Issue: One or more questions have lost their Active / Required / Read-only / Validation Rule conditions. This can occur if an associated field was deleted.
Fix: Re-enter conditions and save.


Invalid Calculated Questions Expressions

1. Issue: Using a text field / select options / lookup to do calculations.

Fix: Only numerical values can be used in calculations. Use the TO_NUMBER() function to change a text value to a numerical value.

Price_Lookup * QTY_select_question - Lookup & Select Question are text values.

TO_NUMBER(Price_Lookup) * TO_NUMBER(QTY_select_question) - Surround each text value with the TO_NUMBER() function to change the value to a number.

2. Issue: If statement expression is missing an else argument.
Fix: IF statements should always contain an else argument.

IF(Question_1 = 1, “pass”) - No else argument.

IF(Question_1 = 1, “pass”,”fail”) - Contains the else argument: "false".

IF(Question_1 = 1, “pass”,””) - Empty value in quotes is also acceptable: " ".

3. Issue: LOOKUP expression does not have 5 arguments.
Fix: Re-create your LOOKUP expression so it contains exactly 5 arguments.

- Invalid, as only contains 4 arguments.

- Valid, contains 5 arguments.

4. Issue: No parentheses around negative numbers.
Fix: Add parentheses around negative numbers.

ADDDAYS(Date_Question,Days * (-1))

Invalid Initial Answer Expressions
