[Zope] stripping values from string

[Mike Doanh Tran]

I have two list from my input form:

ListA: [a,b,c,d]
ListB: [1,2,3,4]

How can i strip ListA and ListB so that the 
first value of ListA will correspond to the first value of ListB
and the second of A to sencond of B and so on:

Example: (a,1), (b,2),(c,3),(d,4) 
I want to be able to populate a database with these values.
I've tried to accomplish this using dtml-in but failed miserably.
    
Can someone give me a pointer on how to do this?

Thanks in advance for your suggestions,

Mike
