Red Hat / Fedora :: Running Mulitple Command Through Ssh Not Working?

I am trying to execute 3 commands stacked together on a remote server. The purpose of the commands are to get the oldest path name, then the filename of the oldest file in that path, and then the date/time of that file.

The command I am running is: stat -c %y $( find -L $( find -L /home/data -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1 ) | grep txt | sort -f | head -1 ) This command works fine if I execute it on the command line of the server. However, when I try to use it in a bash script and execute it from one server on the other server using ssh, the command does not work.

Example:

oldest_file=`ssh -l root $IP "stat -c %y $( find -L $( find -L /home/data -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1 ) | grep txt | sort -f | head -1 )"`

I don't know why the command will execute if I run it straight on the server but not through ssh. I broke it down to just the 2 Find commands and saw with verbose turned on that the path from the first (innermost) Find is not being passed to the second Find so it is not returning a filename which inevitably makes the Stat command fail.

Also, if there is an easier way to do what I am trying to accomplish without stacking these 3 commands like this, then I welcome those suggestions as well since I am a Linux newbie.
