[Setting up to display pdf file into pdf viewer](https://docs.inductiveautomation.com/display/DOC79/Storing+Files+in+a+Database)

I have followed this to the letter but I continue to get a script error, and I can’t figure out why, I have worked on this till I am blue in the face.

`# Check to see if the property that changed was the Selected Value property.`

`if``event.propertyName` `=` `=``"selectedValue"` `:`

`` `# Run the query to grab the file name and bytes using the new selected ID value.`

`` `system.db.runNamedQuery(` `"Read File"` `, {` `"fileID"` `:event.newValue})`

`` `# Grab the file bytes and name from the same row.`

`` `bytes` `=``data.getValueAt(` `0` `,` `"filebyte"` `)`(This is my error “data” is not defined!! )

`` `name` `=``data.getValueAt(` `0` `,` `"fileName"` `)`

`` `# Load the bytes into the PDF Viewer component.`

`` `event.source.parent.getComponent(` `'PDF Viewer'` `).loadPDFBytes(bytes, name)`

You need to store the results of the named query into the `data` object. So `data = system.db.runNamedQuery(``"Read File"``, {``"fileID"``:event.newValue})`
