where do I set the helper IP address?

I'm setting up a stack of cisco 3750 switches. I have several vlans. I'm using the cisco network assistant to configure the switches. Where do I find the settings to set the helper ip address for the vlans?

Helper addresses are typically set on the core switch - sounds like you are setting one up. Helper addresses are applied directly to the vlan itself. Assuming you have created the vlans already:

ssh into your switch (or connect the console cable)
enable
configure terminal
interface vlanX (where X is your vlan number)
ip helper-address 1.2.3.4 (set the helper address here)
