Hi,

I’m trying to create a form where a user can submit 5 of the same  
object (named “ec\_line\_item” with attributes “item\_number” and  
“comments”). I’m doing something wrong because I’m getting this  
error:

NameError in Order#start  
Showing app/views/order/start.rhtml where line #15 raised:  
`@ec\_line\_item[i]’ is not allowed as an instance variable name

Here’s my code:

\<% for i in 1 … 5 %\>

| \<%= text\_field("ec\_line\_item[i]", "item\_number") %\> | \<%= text\_field("ec\_line\_item[i]", "comments") %\> |
| Item Number | Comments |

 \<% end %\>

Any ideas? - Dave
