Show number of tickets remaining for low availability on webform

Is there a way to show the number of tickets remaining on the webform when the low availability threshold has been reached? Basically, if I have the threshold set on a program event so that the low availability alert comes when 5 tickets remain, I want it to show how many tickets are remaining not just that there is low availability. I played around with the language but couldn't figure out what code might need to be inserted in the language to pull this information into the webform.
