Working with arrays could be painful if you could not remove any item after adding them in an array. Arrays are very helpful in programming languages, but in ASP it is not so easy. VBScript does not contains strong functions to remove any item form your array list. Here there is a good ASP code block will be helpfull for your to remove and re-organized your array.

    for i = 0 to arrayLength

            ' If we found our search term in array
            ' we are copying array to a new array list
            myArray(i) = myArray(arrayLength)
            ' So now our first value must be TRUE
            removedItem = True
        end if
    next

    if (removedItem = True) then
        ' Let's make a new array and pass all values
        redim preserve myArray(arrayLength - 1)
