HERE IS A CODE SNIPPIT

Sub randomgen()
Dim randomWeights() As Integer
Dim extraWeights() As Integer
Dim temp() As Integer
Dim lastNumber() As Integer
Dim firstNumber() As Integer
Dim extras(), randoms()

ReDim unsortedRandoms(Cells(2, 2) * 5)
ReDim unsortedExtras(Cells(3, 2) * 5)
ReDim firstNumber(Cells(4, 2))
ReDim lastNumber(Cells(4, 2))
ReDim randomWeights(Cells(4, 2))
ReDim extraWeights(Cells(4, 2))

randomWeights(q) = Round((lastNumber(q) - firstNumber(q)) *
Cells(2, 2) * 5 / totalRange)
extraWeights(q) = Round((lastNumber(q) - firstNumber(q)) * Cells(3,
2) * 5 / totalRange)

temp = RandomNumbers(lastNumber(q), firstNumber(q),
(randomWeights(q) + extraWeights(q)))

end sub

Public Function RandomNumbers(Upper As Integer, _
Optional Lower As Integer = 1, _
Optional HowMany As Integer = 1, _
Optional Unique As Boolean = True) As Variant

end function

END OF CODE SNIPPIT

I want to call the RandomNumber function using the values in those
arrays at index q. What am I doing wrong? I get a runtime error 13 type
mismatch on the RandomNumbers function call.

Thanks in advance,
Phil
