Key binding for use Health

I wanted to be able to remap the h key to something else for using a healthkit. This is the origional bind.

moveMap.bindCmd(keyboard, "h", "commandToServer(\'use\',\"HealthKit\");", "");

I changed it to this:
movemap.bindCmd(keyboard, "f",getHealth);

and the function getHealth looks like this:

function getHealth(%val)
{
if(%val)
commandToServer('use',"HealthKit");
}

I get a console message on the command to server line ActionMap::bindCmd - wrong number of arguments.
the function on the server side in inventory.cs is where I think this calls and has this :
function serverCmdUse(%client,%data)

can anyone tell me what arguments I can add to make this quit complaining?
