Datagrid inserts blank space into textboxes?

[Roy]

Hey All,

Kind of a series of anomalies here with one root source, I believe. I
have an editable, paging datagrid.

1.When one clicks "edit" textboxes open up on row x, HOWEVER, if one
clicks "next page" the textboxes remain no matter which page you are
on. No error messages are shown.
2.After editing data, when one clicks "update" the page refreshes, but
*no* new data is actually loaded into the db. No error messages are
given.
3.If there exists data within an editable textbox and you click "edit,"
the fields on the same row have extra space (blank, empty space)
inserted into them which generates errors when I click "update" unless
I go through and delete the spaces.

Posted is my Update SUB below. Any suggestions are very much
appreciated.

Anyone have any tips? At all?
