jquery function always returns contents of the same table cell, no matter which table cell i click

[coldbohemia]

Hi all.
i have jquery function that's triggered by "onclick" from an html table cell (<td>)
with a class of 'tdcheck':

i then have an alert box that displays the contents of the next table cell which has a class="blank".
this cell is hidden, but i don't think that's the problem.

the function works, but always returns the value of the first table cell in the table,(with the class="blank")
no matter which table cell i click.

every row in the table has one table cell with class=tdcheck ,
and another table cell immediately next to it with class=blank.

can anyone help me with this?
thanks lots in advance.
