Checkbox/Query/Form/Report Help

I need some serious help! I am an Access newbie and I think I am trying to do something more complicated than my skills. Any help will be extremely appreciated!

Here is the situation:

I have a table of volunteer records that record each volunteer's availability and areas of interest, which are checkboxes. The volunteer information area of the form basically looks like this:

Monday Tuesday Wednesday etc.
Morning O O O
Afternoon O O O
Evening O O O

O "Trails" O "Greenhouse" etc.

The "O" designates the checkboxes saying "yes" they are available at that time and "yes" they are interested in that area. I did it in checkbox form because it is the most visual and simplest way for my users to understand the record. My users' thought process is going to be this: I am having a greenhouse clean up this Tuesday evening. I need to run a report of all our volunteers that said they are available Tuesday evenings to work AND said that they want to work in the greenhouse. What I would like next to happen is they load the database I'm designing, click the switchboard to a search form that has the same checkbox layout as the volunteer record. They check Tuesday evening, check Greenhouse, then click run report. Report appears on screen that they can view, which they can choose to print so they can call the volunteers.

I have seen samples of listboxes and dropdown boxes as search criteria on a form, but the additional problem is that my end users are over the age of 65, scared of computers, nice ladies. They wouldn't understand the listbox of fields, and it would be a disaster trying to get them to understand AND/OR statements and the entering of yes/no on a list of search criteria, especially if they have more than one time availability and area of interest that they want to run in one report. Hence, sticking to the easy checkbox format for the never-used-a-computer-before ladies to run the reports they need, spitting out the information to the question they are asking, like "Who are all the volunteers that said they are available weekends to work special events? I need to call them to see if they would work the special event coming up in 3 weeks."

I am completely lost about how to go about doing a checkbox form to run a query of checkboxed data that spits out a report with the results :[ I would appreciate a simple sample or an explanation in layman's terms of the steps involved to achieving the results I would like. I am the type who would like to try to figure this out, so that I learn, but I am completely in over my head with this one :[

All patience and help with this will be greatly appreciated!

Thanks in advance,
