# 2.2.1 Copied Panel is Blank

## What

If a copied dashboard panel is blank, recreate the variables that the panel expects in the destination dashboard, then save the dashboard and reload the panel.

## When/Why

This most often happens when the source dashboard has variables that the panel depends on, but the destination dashboard does not. For example, if a panel relies on `$host` for the server address and the destination dashboard does not define `$host`, the panel can paste successfully but render blank.

## How

Below you'll see the issue:

Fixing the issue requires recreating the variables in the destination dashboard. Grafana does not copy those variables with the panel, so recreate them manually. In any dashboard, open **Dashboard Settings → Variables** to review the variables:

Recreate the same variable names and values in your destination dashboard:

After saving the variables, reload the dashboard. The copied panel should now render with data:
