[ic] Errors in updating [userdb] fields

[Krishna]

Hi list,

I am updating only email, mail receipt, shipping method and
Subscriptions. Through following code. When I am trying to submit the
page I got error

" error saving values in userdb: DBD::Pg::st execute failed: ERROR:
Unterminated quoted string at
/usr/local/interchange/lib/Vend/Table/DBI.pm line 981.  "

Could you please tell me why I am getting this error instead of saving
these values into the userdb. One strange thing I observed is if select
one value from mailing list then it is saving into userdb without error
if select multiple values from the list then I am getting this error
without saving these values in userdb. Could any please copy this code
and test it for login user. Please note that I want only those fields to
be updated for already registered users.


Thanks in advance,

Krishna
