Google Analytics Doesn’t Track Conversions

Hi,

I installed this plugin and use it in my sidebar widget including rainmaker but google analytics doesnt track email signups as conversions and I created a thank you page where it redirects too after signup and I tried I think everything although it doesnt work. I noticed it tracked a conversion 1 time but it doesnt anymore. I think in one of my tests the settings were good but now it isnt.

Can someone help me?

Thanks,
Amr
