I'm working on an Online Customer Form that will replace the default customer registration form for our web store.  I've written a javascript function to search the existing customer records for the email address that is entered (with the hope of eventually redirecting positive matches to the login page or password retrieval after I've got this part working).

Problem is, I'm getting javascript errors when I try to fill out the email field.

If I enter a valid email and then tab out of the field, I get this error message: "nsSelectNodes is not defined"

If I go back into the email field, edit it and tab out a second time, I get this error message: "nlapiSearchRecord: type argument customer is not a valid record or is not available in your account. Please see the documentation for a list of supported record types."
