Re: [Zope] Defining a Variable
That was too wierd. I deleted the External Varible, then re-added it, and all worked well! Now, I just built this new server and transfered over the Data.fs files. Maybe that was the problem??

Apparently, I'm mistaken. I've even tried defining it this way: I didn't see a followup on this post, so I thought I would add my ignorance to the discussion. first, I don't think you can assign a variable name to a python function using tal and then have tal 'call' the function. second, I think what you do want is the get the results of calling getQuote into the variable called 'num', and then use those results elsewhere. I think tal variables can all be first class python objects. If not, any standard python object works -- in other words, a list, tupple, string, dictionary, etc. If you have your own object, it will need to have an iterator method defined for it -- but then, I wouldn't know how to make the new class known to zope. td tal:define=num python:str(11) to make sure that num was properly assigned. What am I missing? Also, if I have a dir called scripts in which getQuote exists, and scirpts is in the path, shouldn't that notation work okay? acquisition will find many things. What does getQuote return though?
