select & delete database rows

[kraadde]

what I wanna to achieve is to have a set of database records listed in a table with a column with checkboxes. the user should be able to tick some checkboxes and by pushing a bitton, delete the corresponding records in the database and in the displayed table.
I tried some coding and below is what I did. however there are always error messages like:
Undefined index: ...and implode() [function.implode]: Bad arguments.
I tried alsmost everything, but I need fresh eyes to look at it...Any help from you guys please...
What I am doing wrong or is ther any better way to achieve what i want? anyone knows a script of some sort?

Many thanks

Check your page and look at the source code.
I use hidden input fields and delete by ID
