Critical Rate issue with Yanfly's Critical Control plugin

[TOWLA]

I am currently using Yanfly's critical plugin, and I can't seem to get my characters to crit like they're supposed to.
I wanted to implement luck as the primary factor for critical rate so I tested out the formula "rate = user.cri + user.luk" but to no avail.
The characters weren't critting at all so I then changed the formula to "rate = user.luk" and changed the characters' luck to 90 to see if that would affect anything.. it didn't. Now I'm left wondering if there's something missing in the formula for it to work correctly. I did snoop around the forums and yanfly's critical control youtube video's comments and found nothing that worked for me.

Would anyone help me figure out the problem?

I have the following plugins installed: YEP_CoreEngine, YEP_BaseParamControl, YEP_DamageCore, and YEP_X_CriticalControl for those of you wondering.

EDIT: Here is the link that I got the plugin from http://yanfly.moe/2015/11/08/yep-26-critical-control/

As this seems to be specifically related to the Critical Control plugin, it needs to be in the section which is for problems implementing plugins.

Would you please edit your opening post and provide a link to the webpage where you got the plugin. That way, if anyone who wants to help needs to check something, they don't have to go hunting.
Thanks.
