Are your table columns defined as the type FLOAT? If you're inserting a floating point number but the column types are strings this still won't work.

eg:

PHP код:

CREATE TABLE tbl (
    vargas VARCHAR(24),   // VARCHAR for names
    afkX FLOAT NOT NULL, // Not VARCHAR
    afkY FLOAT NOT NULL, // but FLOAT
    afkZ FLOAT NOT NULL
) 


Also, why do you only do CheckMySQL(); in one of the if() statements? Shouldn't you do that at the beginning?

If you're not sure if the query is running, try it manually in phpMyAdmin and see if it returns errors.
