lSetPrimitiveParams type error

ive been having this probum, it works but i get a error about the type of prim i tryed adding it and i still get the same errors any ideas?

vector offset = <0,0,1.99611>;
integer oc;

default
{
    state_entry()
    {
        llSay(0, "Hello, Avatar!");
    }

    touch_start(integer total_number)
    {
        if(oc == TRUE)
        {
             
            llSetPos(llGetPos()-offset);
            llSetPrimitiveParams([PRIM_SIZE,<4.947922, 0.017273, 4.458298>,1]);
            oc = FALSE;
        }
        else if(oc == FALSE)
        {
            llSetPrimitiveParams([PRIM_SIZE,<4.947922, 0.017273, 0.380974>,1]);
            llSetPos(llGetPos()+offset);
            oc = TRUE;
        }
    }
}

Try getting rid of the ',1' in this line and in the next one.
