I think you have an excellent point, Todd. I first tried out your code. I produced the same output. So I went to the Embperl site to look up the $cnt variable since I've never used it before with dynamic tables, only the $row and $col ones. The definition states: "Contains the number of table cells displayed so far. (See HTML tag table.)" Seems to me, too, that by definition of $cnt your code should have had the intended 3 rows/columns. I didn't see any actual examples of $cnt on the website, but found one in the examples that came with the installation: [- k = keys %ENV -] [-$maxcol=3-] <table> <tr> <td>[+ $i=$cnt +] </td> <td>[+ $k[$cnt] +] </td> <td>[+ $ENV{$k[$i]} +] </td> </tr> </table> Which only outputs: SCRIPT_NAME /pages/test.epl And looking at the source of the output: <table> <tr> <td> </td> <td>SCRIPT_NAME </td> <td>/pages/test.epl </td> </tr> </table> So I too am confused. Could someone further define $cnt and/or explain why it doesn't work as intended?

I too have taken a closer examination of the eg/x/table.htm example file that comes with the distribution and I am almost certain now that a bug in this version (2.2.0) has been found. It seems that $cnt simply isn't being set. Here is the snippet of code relevant to the $cnt variable from the example file: ############################################################ ####### <hr><h4>Using $cnt and $maxcol (three values per row)</h4> [-$maxcol=3-] <table> <tr> <td>[+ $i=$cnt +] </td> <td>[+ $k[$cnt] +] </td> <td>[+ $ENV{$k[$i]} +] </td> </tr> </table> ############################################################ ####### The actual output, as I am seeing it, is: SCRIPT_NAME /table.htm If $cnt were set as I believe it's supposed to be, the first cell of the table output would be 0 (zero), not empty (NULL). --Todd On Wed, 26 Sep 2007, Gavin Spomer wrote: > I think you have an excellent point, Todd. > > I first tried out your code.
