Excessive Errors In Apache Logs

```
Created a new 2004 format spreadsheet with a single sheet, 3 columns and 7 rows.

A simple parse of each sheet to print out count of row and column numbers
followed by a call to the dump function.

This short script resulted in 143 'Undefined offset' errors in my Apache logs:

0 in excel_reader2.php on line 397
0 in excel_reader2.php on line 400
cellsInfo in excel_reader2.php on line 383
cellsInfo in excel_reader2.php on line 626
in excel_reader2.php on line 521
in excel_reader2.php on line 524
in excel_reader2.php on line 527
in excel_reader2.php on line 530

All seem to be array out of bounds issues but I can't track it down any further.

Have tried to put plenty of tracking information but can't work out what is
happening.

Anyone else seeing this? Any bright ideas?

Reproduce the report with the attached wibble.xls and the described single-sheet, three-column, seven-row input. Start by tracing the accesses reported in excel_reader2.php on lines 383, 397, 400, 521, 524, 527, 530, and 626. Done means identifying why the 143 undefined-offset errors occur and preventing them for this input.
