Check Brand Colour Inconsistencies in InDesign

Hi,

I'm building a script for InDesign to check if any non-brand colours are used in the document. The script displays a palette/dialog and fetches all the swatches. The user then selects the required Brand colours and clicks the button to check any inconsistencies.

The current script prompts the correct number of inconsistencies. The quick navigation dialog box perfectly shows the next object on clicking the 'Next' button. However, the script is not selecting any object. I want the script to find the culprit object and select it, so that the user does not have to find it manually.

Can anyone fix it please.

Thanks.
