What is the difference between an Associations Query Datasource and an Associations Query Guided datasource? I can't figure out which one I need.

Whats the difference between a drop down field and a constant set field?

I've run into an issue creating a data source to list contacts in a group. I know this is relatively simple so I'm expecting I've done something wrong:

I've made a new data source of type "Associations"
Set the source object to be group
Set the association type to be children (as contact is child of group)

After these steps I can't select contact to be the destination object - I'm only allowed to select mailing list contact (which is where contact inherits the association from)

If I pick mailing list contact as the destination object then my data source will successfully list all the contacts in a group, however it would also list all mailing list contacts - and more importantly I can't access any of the contact exclusive properties in a grid using this data source

What is the difference between a sub table and a table record?

I want to set up an object with a property that allows multiple selections from a fixed list. Does this require a special property type or would it be a constant set property - and what control would allow this to work on a form?

-I'm thinking something similar to a radio group that allows multiple selections but I'm unsure if thats possible.

Is there a way to set the creation location of an object to be the child of the object ID referenced in the page URL?

I have a button on the top tool bar of a form thats in a form atom on a page. The button opens a new object form but I'm unsure how to set the creation location to relate to the URL: https://universalvolunteernetwork.com/project-0?object=800

I gather that this may be handled in XFlow in the near future but in the meantime would this require the button to use a short line of custom js?

Whats the difference between Associations Query and Associations Query Guided Data sources?

I want the same layout and branding for every page on my website for a consistent professional look. How do i make a template that will look the same for every page i make with it?

It is often the case that several people want to make changes to forms and grids, which requires object modeller. At the moment we only have one copy of object modeller on one machine so we have to share the PC between several people. Would it be possible for us to get a few more copies of object modeller so we don't have to share?
