I have certain conditions that need to be met by the registrant before they are allowed to actually register for an event.
Can I add conditions to the registration form like...
If income is less than 10K and has two or more kids and lives in xyz city or some other combination of the above then they can register, but if they do not fit the conditions they get a message saying... Sorry you do not qualify.. for more help visit this link.
Also.. can I have different registration rates for kids and adults?
You currently can NOT add conditions in the manner you have described. For giving different rates, you can use custom fee fields. For example, you could have a selection fields where the user selects Adult or Kid. If they select kid, the price can be dropped $X. This type of thing you CAN do. Fields such as dropdown selections, check boxes and radio buttons can all have price adjustments (positive or negative) added to them. Thanks.
