The error is in the last argument you are passing in the list in the call to 
llSetPrimitiveParams. It takes a float and you are passing a vector.

The details about the parameters lists can be found at:

The bit of code would be a bit more efficient if you were to save the result 
from the call to llList2String/llGetLinkPrimitiveParams in a variable at the 
top of the inner loop. In each of the if statements you would then use that 
variable instead of having to do the pair of calls for each of the conditionals.
