I guess you haven't read Svenko's reply good enough.
1. Did you add both binds.net and binds_client.nut in the same folder as the rest of your scripts.
2. Did you add the <script file="binds.nut" client="0"> lines to you script.xml?
3. Does the rest of the script actually load? You can try putting a print into the onScriptLoad function.
Good luck.
