Conditional logic

Allows you to set certain conditions or criteria to be met in order to display an outcome or do an action.

There are 2 parts to conditional logic, IF statements and THEN/ELSE statements.

IF Set your conditions ––––––––––––––––––––––––––––––– THEN If conditions are met, do this ELSE If conditions are not met, do this

See our list of functions you can use to set your conditions.

IF statements

Additional conditions AND/OR

You can choose to add more conditions to your IF statement with additional AND or OR statements.

AND	OR
IF Condition 1 AND Condition 2 AND Condition 3	IF Condition 1 OR Condition 2 OR Condition 3
THEN Do action A ELSE Do action B	THEN Do action A ELSE Do action B
If all conditions 1, 2 and 3 are met, then do action A. If not all conditions 1, 2 and 3 are met, then do action B.	If either condition 1, 2 or 3 is met, do action A. If neither condition 1, 2 or 3 is met, do action B.

In one IF/ELSE logic block, all additional conditions have to either be AND statements or OR statements. We do not allow users to use a mix of AND or OR statements in one logic block.

THEN/ELSE

There are 3 ways to use THEN/ELSE statements:

1. To display a text result

2. As a true false statement

3. To return a number

Display text

True/False statement

Number

Display a text result

Pro tip: Use quotation marks ("") around a string of text to display it as a text result.

Example 1: Giving a specific number

Using a numeric question, we can get a user to input a number. Based on their input, let's show a sentence.

If N1 is certain number, then show some text otherwise show other text

Plaintext	Logic
IF a user has input the number 5, THEN show the text "You have chosen the number 5" ELSE show the text "You have not chosen the number 5"	IF N1==5 THEN "You have chosen the number 5" ELSE "You have not chosen the number 5"

Example 2: Choosing a specific option

Using a radio question, we can get a user to pick a choice. Their choice is seen as a string of text. Based on their choice (i.e. certain string of text), let's show a sentence.

If R1 is certain string of text, then show some text otherwise show other text

Plaintext	Logic
IF a citizen has selected the option “Dog”, THEN show the text “You like dogs!” ELSE show the text “Seems like you like other animals”	IF R1 == “Dog” THEN “You like dogs!” ELSE “Seems like you like other animals”

True/false statement

For complex checkers, we may want to have several layers of checks in a checker. We can use the outcome of a logic block as a condition to be fulfilled in another logic block.

If N1 is certain number, then condition is true otherwise false.

Plaintext	Logic
IF a user has input a number more than 5, THEN condition has been met ELSE condition has not been met	IF N1>5 THEN true ELSE false

Use case example

True/false statements can be used in many ways, here we are using them to tell us if an answer was right or wrong for a question.

Let's first set the right answer for each question using aconditional logic block. If the condition is satisfied (the input was the right answer), then true (correct), else false (wrong).

Next, we need to count the total score. we'll use the function countif to do this: Out of logic blocks O1 to O4, count which are true.

countif([O1,O2,O3,O4],true)

We can now take this total score, and find out if it is a pass or fail. Anything more than 2/4 questions is a pass, else it's a fail.

We used the outcome of logic blocks O1-O4 to help our formula in O8.

Save draft and preview your outcome.

Pass

3/4 correct answers gives us a pass!

Fail

Anything less than 3/4 correct answers gives us a fail:(

True/False statements can also be interpreted as 1/0 by logic blocks.

Return a number

In quiz formats, it's may be more useful to count if an answer was Correct/Incorrect based on how many points are awarded. This would help simplify our calculations of their total score.

If N1 is certain number, then give 1 point otherwise give 0 points

We can then use acalculated logic block with the formula below to tally up their total score out of 100:

((O2+O3+O4+O5)/4)*100

The outcome would look like this:
