AOL Campaign Reports vs. Hitbox Enterprise Reports

AOL's actual clicks do not match Hitbox Analysis

[Bishop]

AOL's ASIS reporting tool is showing double the number of clicks delivered compared to my Hitbox Enterprise campaign report. My Hitbox code is at the top of my page so I know it is being loaded first. Does anyone have some insight as to why this may be occurring?
AOL claims 37,556 clicks
Hitbox Enterprise shows 17,924 clicks.

I thought the cache may affect the numbers but with Hitbox, when the page is viewed, the code should run and register a hit. Any insight would be greatly appreciated.

Thanks in advance!

AOL campaigns always bring to the for tracking problems - usually (in my experience) AOL reports the higher figure but all tracking software underreports AOL figures. It's not an easy place to be in. I'm sure it is a cache issue - why don't you try getting them to bill you for your tracked clicks and a bit of the difference?
