Plugin not working – is it my theme?

Hi,

This plugin does exactly what i need but im unable to get it to work.

ive included the customisations i have made in my functions.php below but its also worth noting that i use the woocommerce table rate shipping plugin aswell so not sure if this causes an issue?
