Help needed: trying to update custom Entity field in contact

Hi everyone,

I'm trying to use SuiteScript to update a custom Entity field within a contact upon creation of that contact. I've been following the documentation and examples dotted around, even so far as to download and use Eclipse IDE with JSEclipse plugin.

The problem is I don't fully understand how to write the script, OR how to properly add it to NetSuite. I wonder if someone ca give me some help, in laymans terms?

Here's the script I've put together.. it's very simple at this stage:

filename: methods.js

function addPasswordToContact(type)  {   if (type == 'create')   {    var record = nlapiGetNewRecord();        record.setFieldValue("custentitymember_password","testtest");   }  }
