Help me correct this Expression Language syntax

I created a HTML Markup through Page Composer.

My goal is to check if the batch number value is equal to batch description value.
For instance:

Inputs
Batch Number: 2535
Batch Description: 2535

Output
HTML Markup: duplicate

The syntax is: #{bindings.BatchNumber.inputValue == bindings.Description.inputValue ? 'duplicate' : 'unique'}

However, it always return the 'duplicate' regardless of the value of batch description

Please see the screenshot below:
