Cant get variables to carry over... HELP!!!

I am new to MODx and am having issues with things that I am sure are very simple. Below is my problem...

I have created a snippet and this snippet is very simple. its checks to see if a varriable exists, and if not, shows a form. When I submit that form to the same page, it should revert back to just show that varriable... It’s not doing that. I have tried submitting the form with POST, GET, REQUEST. Still no luck. I have placed the snippet in the TV, I have placed it in a chunk. I do not know what I am doing wrong. I also have submitted the form to different places, such as the actual path, the relative path, the rewritten-url path and the MODx var ([~page_num~]). Please help.

My questions:

1. When submitting a form, I would like to use POST. Can I?
2. Whan I actually submit the form and want it to go to the same page or any other page, how do i do that in MODx?
3. When recalling a varriable, I would normally use $_POST[var]. Is this correct?
4. When assigning sessions, Do I do anything different that the usual $_SESSION[var] = $_POST[var]; ?

Thank you all for this great system. I feel that when I get the hang of it, I will really benefit and become a better developer.

All of it should work if you call the snippet uncached:

or make sure the page you call it on is not cacheable.

There are some more snippet tips here: http://bobsguides.com/modx-snippet-faq.html

Thank you both so much... I have learned so much in just the past six hours playing around and browsing the forums... Great FAQ by the way...

Both responses paid off for me.

I look forward to learning more as I grow with MODx.
