Appending to elements in a Bash associative array - arrays

Question

My name is Mike and I am a total noob at Bash programming. With that being said, please don't chew me to a pulp. Here's my scenario. I'm importing a csv and processing it line by line. It looks up information in AD and pipes that result to a variable $ADresult1.
I then take that output and send it into the array.
declare -A arrmail
arrmail[$ADresult1]="$v1, $v3"
appendvar+="; ${arrmail[$ADresult1]}"
if [ ! -z "${arrmail[$ADresult1]}" ]; then
echo ${arrmail[#]}
else
echo ${arrmail[#]}="$appendvar"
fi
Now in my CSV file, the var $ADresult1 has more than one entry that is the same, however each element should be different.
For example: The first line might contain arrmail[p100]=Y2K, Y2J
The second line might arrmail[p100]=GGG, GG1
My question would be how to combine the elements from the first line and second line into one line of output and/or if this is possible.
For instance arrmail[p100]=Y2K, Y2J; GGG, GG1
If needs be, I can post the whole entire script for a bigger picture.
Here's the script.

I know this is a lot. I've been working on this for a long time and I'm trying to gain a greater understanding of how to use and manipulate arrays. Also if you have an recommendations on books covering the subject, I'll be happy to review those also. Thank you in advance for all the help.
