This is the line that is erroring

    if ($checkboxvalue[$t] == 1)

This is the error

Use of uninitialized value in numeric eq (==) at BPP/BILL.pm line 148.

I declare @checkboxvalue = () as such.

Should I do this also $checkboxvalue$t = 0; ?
I dont' understand why it is "uninitialized".

Update:
It seems that when I click the checkbox the onValue is not being set. So below is my declaration of the Checkbutton

    $checkbox[$t] = $bill_table->Checkbutton(-variable=>\$checkboxvalu
+e[$t]);

Perhaps -variable is not what I should use. I'm going to read more on the Checkbutton options
