I want to generate a select-field with options:
50
55
60
...
80
So I tried:
<% @options = [] %>
<%= 50.step(80, 5) { |a| @options = a}%>
<%= select("DL","bandwidth", options) %>
No success at all!
Any hints?
Thanx

If so, you could do: @options << [a,a] Also, your second <%= should be a <% and you need to decide whether (@)options is or is not an instance variable :-) David -- Q.
