(See the best response by Pirion.)
Code:
mob/player/verb/PressD()
    usr << "Click <a href=?src=\ref[src];action=start>here</a>!"
mob

    player

        Topic(href , href_list[])

            switch(href_list["action"])

                if("start")

                    usr << "Starting the game..."

                else

                    return ..()


Problem description:
Hello all viewers, so I've decided I want to use grids to catch the topic of a hyper link I place inside a cell.
I can catch the Topic when it automatically goes to the client and I can reroute the Topic to an object..... but I can't reroute and catch Topic at the same time, so I must be doing something wrong!
So I tried to use an example from the reference but it gave me the same error I was getting before, if someone can show me how to catch a topic when it is rerouted to a different object it will be appreciated, preferably without the need of a list!
Have no restraint in whipping me about what I'm doing wrong as-well O.o, thanks.

Heres the error:

runtime error: bad index
proc name: Topic (/mob/player/Topic)
source file: Dialogue.dm,51
usr: Jlxati (/mob/player)
src: Jlxati (/mob/player)
call stack:
Jlxati (/mob/player): Topic("src=\[0x3000000];action=start", /list (/list))
Check

I used this code and there were no error for me. This is the one that is in the source file mentioned?

Yeah your right the code works fine, I was careless forgot to remove the first Topic proc i wrote. I also figured out what was the problem with my hyper-link before I didn't realise,
 <a href=?src=\ref[src];action=start>

and
<a href=?src=\ref[src];action = start>

are treated differently must be sensitive to white space >_> once again thank you!
Also do you know how one would create a hyper-link that catches just a topic name from a an object set as the src, instead of a list
i.e:
"<a href=?src=\ref[src];action> Ill eat your entrails on mah tummeh, Time Child!!!</a>!"

But with 
src=\ref[src]
defined. Thanks in advance!

Sorry - I'm not sure what you want to do?

It seems like your asking for the href param?

Urm..
    player

        Topic(href , href_list[])

            switch(href)

                if("start")

                    usr << "Starting the game..."

                else

                    return ..()


I only want to use the first passed variable to check if the topic was caught, instead of the second variable which is a list. But I don't know how to construct the sentence in html, i tried looking it up but found no example.
<edit>
Yeah basically what you said!

First off you can't parse a second string using ;

The first string must always have ? before it every extra one uses & , like below

"<a href=?src=\ref[src]&action=haha&blah=1> Ill eat your entrails on mah tummeh, Time Child!!!</a>!"


Using a list is fine and easy.

"<a href=?src=\ref[src]&action=eathim> Ill eat your entrails on mah tummeh, Time Child!!!</a>!"

    player
        Topic(href , href_list[])
            switch(href_list["action"])
                if("eathim")
                    usr << "The eating has begun!"
                else
                    return ..()
