I am away from a compiler, so I cannot compile and test this. If you are willing to do the legwork, I can fix any errors with it.

dcmd_money(playerid, params[])
{
   // Declare a new string to hold the player input.
   new stringParameter[128];

   // Ensure that sscanf has received valid parameters. I have added the space following the "s" to trick sscanf into thinking there are more parameters.
   // Ex: "/money dm test", sscanf will stop processing after the space, and "test" will be discarded. If you instead are interested in the entire string (including spaces),
   // use "s" or "z". Details are at the links I've provided.
   if(sscanf(params, "s ", stringParameter)) return SendClientMessage(playerid, RED, "[ERROR]: You must enter a string!");

   // Search for the text in the parameter. The function declaration is as follows:
   // strfind(const string[], const sub[], bool: ignorecase=false, index=0)
   // Parameters followed with an equals sign are OPTIONAL.
   if(strfind(stringParameter, "dm", true) != -1) GivePlayerMoney(playerid, 100);   

   return 1;
}

These links both helped immensely when writing this code. The wiki should be the first resource you refer to while coding.
