Hi
I thought I had resolved this problem but I am intermittently
the receving the warnings below.
This code consist of a 1) HTML form, 2) a display function on the HTML form and
3) a process to manage the form input.
Can you show me what I am doing wrong and or how to correct it ?

        check_unit_field($field_unit);//funtion to validate user entered numbers or message sent
 
     //insert statement goes here
 
    }
 ?>

I have added the code below to the process to get rid of
the errors but this creates another problem where the
for loop can't extract the data from the arrays.

//create array A
$fee_unit = array($fee_unit);
$fee_money = array($fee_money);
 
//create array B
$fee1_unit = array($fee1_unit);
$fee1_money = array($fee1_money);

Hi
Thanks for responding.
I altered the values assigned to $all_array used by the return starement.
This seems to be working and I have not received any error or warning messages yet.
Working change

$all_array = array($fee_choice, $fee_unit, $fee_money, $fee1_choice, 
$fee1_unit, $fee1_fee, $fee2_choice, $fee2_code, $fee2_unit, $fee2_describe, 
$fee2_money, $fee3_choice, $fee3_code, $fee3_unit, $fee3_describe, $fee3_money);

I think this can be considered resolved, unless you think other wise.
