We are trying to make a 3rd party connection for the Lokard safety stock calculator and I am experiencing trouble! They want

TBLPREFIX=;
MySql table reference used by your OxCommerce (also zencart) instance. Default table prefix is empty but check with your MySql database to get the right prefix, eg TBLPREFIX=zen_;

My programmer is saying there is no table reference, can anyone elsoe shed some light? Setting this up has been a real pain in the a*se!

Thankyou
