I have a link\_to\_function on one page to go to this edit screen with  
this link\_to\_function.

\<%= link\_to\_function ‘cancel’ do |page|  
page[:“work\_show\_#{work.id}”].hide  
end %\>

When I click on the edit button it says,  
missing ) after argument list  
[http://localhost:3000/](http://localhost:3000/)  
Line 2

If i take out  
page[:“work\_show\_#{work.id}”].hide

it works fine. Any ideas why it it saying there is an issue?

Anyone?

I can also do:

\<%= link\_to\_function “cancel” do |page|  
page.hide  
end %\>

When I click cancel it gives me an error which is expected as there is  
no element to hide. If I put any value say page[:foo].hide I get the  
same error as above.
