I have a “javascript\_include\_tag” including a Javascript function.  
I have a function being invoked via a helper in the same view, which  
prints  
out a script tag that uses the javascript function above.

Problem is, the function being invoked via the helper can’t find the  
javascript function included in the “javascript\_include\_tag”.

I hardcoded the javascript that exists in the “javascript\_include\_tag”,  
into  
the head of the view… and the helper had no problem finding the  
method.  
So… it seems that the helper is being invoked before the  
“javascript\_include\_tag” declaration ?

Does this seem correct ?

Why not just include the javascript file in the tag? Can you post  
the code you are using?

Jonathan… SVN problem, and my Javascript wasn’t updated. It all works  
now.  
One sec… going to go bury my head in the sand real quick 🙂
