ForLoop Nesting

I have a question about ASP code. I'm not figuring out what the problem is.....driving What i'm trying to do is nesting 2 forloops into each other calling different variables, but i get an error like "type mismatch". Do you know whats wrong??

This is the code:

<%
Dim specialisme(5)
specialisme(1) = "Radiologie"
specialisme(2) = "Anesthesiologie"
specialisme(3) = "Cardiologie"
specialisme(4) = "Chirurgie"
specialisme(5) = "Dermatologie"

Dim Radiologie(4)
Radiologie(1) = "Radiologie MRI"
Radiologie(2) = "Radiologie CT"
Radiologie(3) = "Radiologie Mammografie"
Radiologie(4) = "Radiologie Echografie"

..........
