You need to thread the query (you can do it without threading, but i highly recommend you do so):

Here's what you need:

Look for:

3.11 cache_get_value_name
3.12 cache_get_value_name_int
3.13 cache_get_value_name_float


There's a few examples on the wiki page i linked you on how to thread queries.
