Hi,

It's been a long day, can someone put me out of my mysery:

I have a multi-dimentional array, (below) and I need to get the index sequence number of a specific element.

For example, I am looking for Household '15' so I want the result to be 12.

brain ache.  top points.

Array
(
    [HOUSEHOLD] => Array
        (
            [0] => 2
            [1] => 3
            [2] => 9
            [3] => 20
            [4] =>
            [5] =>
            [6] =>
            [7] => 5
            [8] => 8
            [9] => 7
            [10] => 6
            [11] => 19
            [12] => 15
            [13] => 10
            [14] => 18
            [15] => 1
            [16] => 17
            [17] => 16
        )

    [NAME] => Array
        (
            [0] => SJ of Eastbourne
            [1] => New Player
            [2] => New Player
            [3] => WB of London
            [4] => ...
            [5] =>
            [6] =>
            [7] => New Player
            [8] => New Player
            [9] => SJ of Eastbourne
            [10] => New Player
            [11] => SJ of Eastbourne
            [12] => WB of London
            [13] => New Player
            [14] => SJ of Eastbourne
            [15] => New Player
            [16] => SJ of Eastbourne
            [17] => SJ of Eastbourne
