insert in 2 demensional array

Hi,

i am using a two dimensional array like this:

Dim $formfields[3][2] = [["element1", "data1"],["element2", "data2"],["elemnt0","data0"]]

there can be x elements.

My problem is that i need to have a certain element at the first position (the order of the other elements does not matter, only on certain element hast to be at position 1).

Dim $formfields[3][2] = [["element0", "data0"],["element1", "data1"],["elemnt2","data2"]]

I wanted to check if a certain element exist in formfields and if it exists, i remove it and re insert it at position 1. If it does not exist, i just want to add it at position 1.

I tried several things, but i could not get this done correctly, due to problems with the array dimensions after removing/adding...

Can anyone show me how to do it right?

thanks in adnvance,

Edit:

here is what already works:

Func _AddOrUpdateFieldIn2DArray($array, $fieldname, $data = "")
    $iIndex = _ArraySearch($array, $fieldname, 0, 0, 1, 2, 1, 0)
    If $iIndex <> -1 Then;the field exists
        If $array[$iIndex][1] = $data Then          
                      ;already up to date
        Else
            ;update
                     $array[$iIndex][1] = $data
        EndIf
    Else
            ;add
            ReDim $array[UBound($array) + 1][2]
        $array[UBound($array) - 1][0] = $fieldname
        $array[UBound($array) - 1][1] = $data
    EndIf
    Return $array
EndFunc  

and would like to have something like this also:

Func _AddTobeginningOf2DArray($array, $fieldname, $data = "")
;adds $fieldname to the beginning of the array, removes $filedname from other positions if it already exists

    Return $array
EndFunc
