Hi Harold, the currency symbol isn’t set in Polyboard, it comes from the currency your Windows operating system is using. But you can change this. I’m using Windows 10 and if I search for ‘currency’ I get to this Region settings page:

In the ‘Region’ settings, change the language to English (India), then select Additional settings:

Then select Currency and you should be able to select Rupees:

All the best…

EDIT: now I’ve just got to remember to change it back!
