### Condition Builder page

Use the Condition Builder page to build an inline condition. This page appears only in the Condition Editor.

Build an expression in the Condition Builder as follows:

1. Select Comparison Expression to build a comparison expression or select Unary Expression to build a unary expression.
2. If you chose Comparison Expression, do the following:

1. In the Operand field, enter the name of the operand you want to compare to a value. Alternatively, drag an item from the Variable Structures tab on the right to the Operand field.
2. In the Value field, enter the value against which to compare the operand. Alternatively, drag item from the Variable Structures tab on the right to the Value field.
3. Select a comparison operator from the Operator list.
4. Go to step 4.

3. If you chose Unary Expression, do the following:

1. Select or deselect the Not check box to indicate whether to evaluate the expression as true or not true, that is, to specify whether the expression should be enclosed by not().
2. Enter an expression in the text field, or construct it by dragging items from the Variable Structures tab on the right.

4. Do either of the following:

- Click Add to add a new statement to the expression in the Condition Expression field.
- Select a statement in the Condition Expression field, then click Update to modify the statement.

5. Click Test to test the expression in a running server, or click OK to insert the condition in the message flow.
