# Editing parameter names

By default, the parameter name is the same as the input column name. However, you can change the parameter name as needed and then associate it with an input column. This is useful, for instance, when you need to shorten attribute names. For example, `EstimatedTimeOfArrival` can be abbreviated to `ETA`.

To edit a parameter and associate it with an input column:

1. In the **Parse Expression** pane, edit the parameter name as required.
2. From the **Attribute** drop-down list, select the desired input column.
