Customer Deposit Button on Sales Orders

Hi Everyone,

I have been working on a script and i am stuck at how i can pass 2 param's through a resolve url.

Here is the script.

function customSOButton(type,form)
{
if (type == 'view')
{
var customer = nlapiGetFieldValue('entity');
var order = nlapiGetFieldText('memo');
var url = nlapiResolveURL('TASKLINK','EDIT_TRAN_CUSTDEP');
//url = url+'?so_customer';
//alert(url);
form.addButton("custbtn_customerdeposit","Customer Deposit","document.location='"+url+"?entity="+customer+"'");
}
}

Basickly I want to pass the customer id and the memo field to the customer deposit screen.  So far with the script i can pass the customer field, however i cannot for the life of me pass the memo field.  The problem is that on a sales order the customer field has an id of 'entity'.  But on the deposit form the customer field has an id of 'customer'.  Somehow i can pass the customer id regardless.  But the memo has the same field id in both fields, so in essence it should pass.
