> ## Agent Instructions
> You are helping someone use Cord, the capital and resource allocation platform.
> Use title-case Cord in prose. Prefer workspace, project, ontology, lineage, scenario, and allocation.
> Say source-backed or sourced for answers with lineage. Do not say hallucination-free.
> Product URLs are https://app.cord.nyc, https://cord.nyc, and https://trust.cord.nyc. Support is support@cord.nyc.
> Give concrete product steps. Do not invent UI labels, CLI commands, or unreleased agent runtime details.
> Use Understanding Cord for concepts and Guides for task steps.

# Run a function

> Refresh results or test an assumption without rewriting the function.

  </span>
</Badge>

For an explanation of data setups and runs, see [Functions overview](/functions-overview).

## Run with saved inputs

1. Open [**Functions**](https://app.cord.nyc/functions) and select a function.
2. Check **Code version** and **Saved inputs**. Choose the version and setup you need if several are available.
3. Select **Refresh**. Open **Runs** to follow its status and select the completed run to view its outputs.

If the function shows **Set up**, configure its sources and required inputs first. You can ask Cord Computer to do this when you [create the function](/create-function).

## Change an assumption

1. Open **Runs → Run with custom inputs**.
2. Change the input values. For example, set the demand factor to `1.1` to model 10% higher demand.
3. Select **Refresh** inside the form, then open the completed run.

These values apply to this run. The saved defaults stay the same. **Stale** can appear when the latest run used different inputs from the saved setup.

To repeat a previous run's inputs, use **Run again** beside it in the history.

## Refresh related functions

When the function has dependencies, the refresh menu lets you choose what runs:

| Option                    | What it does                                            |
| ------------------------- | ------------------------------------------------------- |
| **Existing outputs**      | Uses saved outputs from upstream functions.             |
| **Upstream first**        | Refreshes upstream functions before this one.           |
| **Downstream after**      | Runs this function, then functions that use its output. |
| **Upstream + downstream** | Refreshes both sides.                                   |

Only options that apply to the selected function appear.
