# Start Condition and Set Condition

*Start Condition* sets the reference that should be used for comparison.

*Set Condition* sets the condition.

### Adding Multiple Conditions

You can add multiple conditions by simply adding multiple *Set Condition* building blocks to the *Start Condition* building block, like so:

### Chaining Conditions

You can chain multiple *Start* and *Set Condition* building block pairs, like so:

Also, as you can see above, you can add one *Set Condition* building block for just **one** condition or multiple blocks for multiple conditions.&#x20;
