Subject: [Zope] Calculations - more dumb questions.


I was reading earlier postings about 'variables' or the lack of them in 
Zope and I went off and investigated Python Methods and External Methods 
and I've got them working  ... but .. I can't figure out how to use them to 
solve my problem ...

I have an SQL method and I've generated the form and results report using 
the standard wizard - absolutely wonderful.

Let's say I have an input variable, called 'customer' on the form which is 
passed to the SQL method. BUT I want to intercept that variable and do 
something with it, let's keep it simple and say that I want to put the 
string "CT" in front of what the user enters (I know that's trivial but for 
the sake of argument).

I can write an External Method or Python Method which does the necessary 
but it returns the string back to the calling object as text which is 
displayed by the browser.

Can anyone tell me how to get that new string back into the variable 
'customer'.

Please :-)
