You can use a custom format in the text box where you do
not want to see the 0s. It depends on how you are
formatting the values that are not zero though. E.g. If
the values are displayed with the Currency format, then your
custom format could be:
$#,##0.00;($#,##0.00);"";""
If the values are simple integers, the format could be:
0;;"";""
