I don’t know if this is a ruby only question or a rails question. I  
have a helper class that updates the view based on the info from the  
div tag. This information is passed using the link\_to\_function. But it  
doesn’t work. I don’t know how to access the page elements. Also, is  
the if statement syntax correct for ruby? Thank you in advance for any  
help.

Is it if x1 == ‘x1’ or is it if x1 = ‘x1’?

module VideosHelper  
def hide\_and\_reset(div, div2)  
update\_page do |page|  
if page[div].title == ‘show’  
page[div].hide  
page[div].title = ‘hide’  
else  
page[div].show  
page[div].title = ‘show’  
end  
end  
end

\<%= link\_to\_function image\_tag("graphics/ select04.gif", :alt=\>'Programming', :size=\>'100x20', :border=\>0), hide\_and\_reset(:select02\_div, :select01\_div) %\>

The equality operator in Ruby is ==

As for the question regarding accessing and updating page elements  
that is better suited for the Rails talk list. However, the key to how  
to work with elements might be at
