Wrong variable

Hi SystemDevil, i used your implementation, and it´s perfect!, but i´ve found on lines 227 and 229, that you call $cell_format which should be $value to work ok.

<pre>
} else if ($cell_format=='date') {
</pre>


Should be

<pre>
} else if ($value=='date') {
</pre>


Apart from that it´s working really good, again, million thanks for sharing!
