Facebook Pixel - Conversion Tracking Help!

I am trying to add purchase conversions when a customer gets to the order confirmation screen to feed to my Facebook pixels.

I am very incompetent when it comes to this - but I found this FB article calling out the script to put on the confirmation page.

https://developers.facebook.com/docs/meta-pixel/implementation/conversion-tracking

... ...

I assume I change value to 0.00 from 30.00 - but I continue to get errors.

First error reads: Expected an identifier and instead say ‘<’.

Second error reads: Expected an identifier and instead saw ‘…’. Unrecoverable syntax error (66% scanned)

Just trying to track conversions and really could use some support! Pixels are installed everywhere else on the site and working properly.. just can’t figure this out.

Thanks in advance!
