Where's the leak? There are two compression joints plus a connection to the tank. Which one is it?

This tells me nothing. Please be more specific. The material the pipe's made of. The connection it's leaking from and toilet supply lines do not have caps.
Until I can understand what your problem is I can't be of much help. Regards, Tom

Pipe is going to toilet tank this pipe is below the shutoff valve does this help

Are you saying that there is a threaded galvanized pipe with a chrome escutcheon plate around it coming up through the floor and connecting to a threaded 1/2 thread to 1/4" compression straight stop and that it's leaking at the threaded connrction? I'm still attempting to visualize your complaint. Regards, tom

I think I understand: he has a "stub-up" (from the floor) or "stub-out" (from the wall) which has a shutoff valve cut into it - but the original pipe continues a little bit past the valve, and is capped off; it is that cap that is leaking.

Is that correct, gayatri?

EDIT: Actually, I changed my mind. ;) I think he means it's a stub-UP with a straight valve, and the bottom half is leaking (whether FIPS or compression)

'Til we get this straight, lets try a different tack:

gayatri, just because the water SEEMS to be coming from a certain spot, it doesn't mean that's exactly where the water's coming from. Water has a nasty habit of travelling quietly - sometimes a few inches, sometimes several hundred feet - before it "appears". Therefore, take a paper towel and dry the whole thing very well. Then check carefully where the water is coming from. Don't just feel with your hand; shine a flashlight on the area, and see if you can catch the "glint" of the water. By doing this, you will hopefully be SURE of where the leak is coming from.

Next, anser these questions for us:
1) Is the pipe sticking out of the wall behind the toilet, or the floor next to it?
2) Look at these two valves:

Is yours like the one on the left (where the knob and pipe are on the ends, and the toilet tube is on the side), or the one on the right (where the pipe and toilet tube are on the ends, and the knob is on the side)?
3) Can you tell what the pipe is made of: copper, galvanized, or something else?

One final tip: if you have access to a digital camera, posting a picture of the problem would be very helpful.
