Command execution whilst claiming kit not working for non-admins

Hi - I've a prestige kit that contains an item to give RP upon claim.

The command is /rp add %username% <value>

This works ... but only if an administrator claims the kit... Checking (server rewards plugin) it's clear that you need Admin perms to execute this this command. 

Is there a way to have the kits plugin execute commands as "admin" authority so that default players can claim this item ? 

Thanks

Hi. I can assume that you are using the chat command, and you need to use the console command (they are run on behalf of the server)

Hey - really sorry for the delay responding ... Still an issue - 2 players have both just levelled up and can now claim this kit... They get the contents but not the RP

But when an Admin account claims the kit the command executes no problem !?

Excellent thanks
