Overview
Use a  node to manipulate data that is passed to it. Calculate nodes have their own attributes, which can reference incoming data via expressions using one or more of the 115+ functions available in PhixFlow. ExampleClick to play the following video that shows an example of using a calculate node in an actionflow. 
The video shows an actionflow that opens a new screen containing a dynamic text field. It then populates the dynamic text field with a message, which is set in a calculate node attribute. The steps for are: - Drag a calculate node from the toolbar and drop it into the actionflow diagram.
- Name the calculate something meaningful, e.g.
Set Message - Disconnect the
 node from the  . - Connect the to the node.
- To pass data into the actionflow, go to the Inputs section on the left. Connect the component input connection point ScreenToOpen to the calculate node.
- Click on the calculate node to open its properties.
- In the Attributes section, add a new calculate attribute and set:
- Name to
Message Expression to: "You have successfully set up a calculate node" |
- Map the calculate attribute to the dynamic text field on the screen as follows:
Right-click on the connection and click Configure Mappings. - Drag the Message attribute from the calculate node, on the left, to the Message attribute on the open screen, on the right.
- Close the mapping screen.
- The actionflow configuration is complete.
After configuring an actionflow, always test the actionflow to make sure it works. |

Output Attributes Calculate actions process data using expressions; see pages in the topic Expressions and PhixScripts. This section has a toolbar with standard buttons. The grid contains a list of the expressions that the calculate action will perform. - To add a new expression, in the section toolbar click
 to open a new expression and set the properties. - To edit an existing expression, double-click it in the list to open its properties.
- To remove an expression, select one and in the section toolbar click
 . - To reorder an attribute, drag and drop the attribute into the desired position. Alternatively, double-click to open its properties and update the Order field.
- Click . PhixFlow opens the properties for a new calculate attribute; see Calculate Attributes Properties, below.

Make sure you select the same data type as that of the attribute to which you are mapping; see Understanding Data Types. |
| | Order | Where the calculate action runs multiple expressions, enter a number to indicate the order in which this expression will be run. Remember that an expression that generates a value must run before any expression that uses the value. | | Expression | Enter an expression. To work in a larger popup window, click  . See also: |
Input ConnectionsThis section has a toolbar with standard buttons. The grid contains a list of the connection points that connect into this calculate node. - To add a new input connection point, in the section toolbar click and set the properties.
- To edit an existing connection point, double-click it in the list to open its properties.
- To remove a connection points, select one and in the section toolbar click .
