Ok, so it is a good idea to try some javascript tutorials to get the hang of it first. Javascript can be a pain to debug from my experiences. A few things that you may find helpful to help with your tasks:
- onclick() *event
- visibility or display *attribute
- disabled *attribute

If you need more help post some code, and somebody can have a further look.

Hey...
thnaks for the comments...
I am working through it....

I also hav another doubt of click and drag image....
its like i have and image , when its drag and dropped in a table, it must get snapped to it...
How do i snap the images to the table..?
Ur help will be much appreciated..
thanks...

I am not entirely sure what you mean by the drag / drop of the image. Is this while you are designing the page or do you actually have a feature on the website to allow drag / dropping?

HI,
Its not in the website...
its for a game..
Drag and drop the elements in the table...once this is done and press enter, any the particular action take place...
eg: drag and image to a table , once the image is fixed and enter or submit is clicked, another image displays by the side..
