[Urgent] Need Help In Setting Up CPV Lab Tracking

Hi Guys, hope y'all is having a wonderful day,

I just installed cpvlab 2 days ago and i have been trying to track my leads and conversion from a free traffic source (facebook for example) using google url builder and cpvlab, but i could not find a working solution.

Let me Explain, am trying to pass a token form google builder url to my cpv lab tracking url.

For Example

This is Google url builder link (which i will be spamming)
http://mysite.com/?utm_source=Facebook&utm_medium=FacebookGroup&utm_campaign=FacebookGroupBatchA

And here is my cpv lab link that will receive the token from the url above.
http://mysite.com/base.php?c=5&key=99877f3c748c76077cbe4c3c4f3b1346&utm_source={source}&utm_medium={medium}&utm_campaign={campaign}


In simple words, how do i pass the require value from one url to another url?

Thanks For Reading.

Bump for reply,.
