  Concept: Adding Conditions in Expression Builder
layout: subsection
---

You can specify how your orchestration proceeds under particular conditions anywhere in Orchestration Builder where you see the <b>Add condition for value</b> button on the right of an expression.

Each individual condition consists of 2 values and a relational operator. To define a condition:

1.  Use Expression Builder to define the first value.
2.  Select a relational operator from the <b>Condition</b> drop-down menu.
3.  Use Expression Builder to define the second value.


The values you define can use data from elsewhere in the orchestration. Orchestration Builder uses the operator to compare the values and determine whether the expression evaluates to true.

<b>Note:</b> You can compare numbers directly using member functions of the `Number` type.

You can have more than 1 condition in a conditional statement. For multicondition statements, select 1 of these options:

-   <i>All of these conditions must be met</i>: evaluates the conditions using a logical `AND`.
-   <i>One of these conditions must be met</i>: evaluates the conditions using a logical `OR`.


Example: if you define multiple conditions and select <i>One of these conditions must be met</i>, Orchestration Builder considers the entire condition to be `true` if any of the conditions evaluate to `true`.

Under <b>If conditions are true</b> and <b>If conditions are false</b>, use Expression Builder to define the output of the conditional.

Note that the conditionality is nestable. You can add conditions to the expressions that define your conditions. When you do so, Orchestration Builder darkens the interface behind the current window to remind you that you're no longer working on the primary condition. The background darkens further with each level of nesting.
