Array not printing values if used in a loop

Hello!

I'm making an English to Morse Code translator and I was able to mostly get it all working by looking through older posts here; however, I have one small problem.

When I run it it's just printing spaces for where the characters should be. It runs the right amount of times, and if I try to individually print out of the array it works, but when I try to have it cycle through to translate I get the problem.

What I am running/output:
Code:
[acolem26@ats-cis project8]$ ./morse "a b c"
 SP  SP  EOT

My code:
Code:
#!/bash/bin

declare -A code
code[A]=".-"
code[B]="-..."
code[C]="-.-."
code[D]="-.."
code[E]="."
code[F]="..-."
code[G]="--."
code[H]="...."
code[I]=".."
code[J]=".---"
code[K]="-.-"
code[L]=".-.."
code[M]="--"
code[N]="-."
code[O]="---"
code[P]=".--."
code[Q]="--.-"
code[R]=".-."
code[S]="..."
code[T]="-"
code[U]="..-"
code[V]="...-"
code[W]=".--"
code[X]="-..-"
code[Y]="-.--"
code[Z]="--.."
code[1]=".----"
code[2]="..---"
code[3]="...--"
code[4]="....-"
code[5]="....."
code[6]="-...."
code[7]="--..."
code[8]="---.."
code[9]="----."
code[0]="-----"
code[ ]="SP"

str=$1

for (( i=0; $i < ${#str}; i++ ));
do
     printf "%s " "${code[${str:$i:1}]}"
done
printf "%s\n" EOT

If I do something like

Code:
printf "%s " "${code[A]}"

It prints off the corresponding Morse code so I assume the issue isn't with the array but with how I am substituting and I'm not sure how to fix it.

NAME
morse - A robotics simulator based upon the Blender Game Engine SYNOPSIS
morse [command] [options] DESCRIPTION
Morse, the Modular OpenRobots Simulation Engine, uses the Blender Game Engine to provide a general purpose robot simulator. A robot and its environment are defined in Morse by creating a model in Blender. Actuator and sensor objects are attached to a model, and may be inter- acted with via a variety of middleware protocols. Simulations can be programmed via Python scripts or inside of Blender itself. Currently supported middleware includes YARP, MOOS, ROS, Pocoslibs, as well as a plain socket interface. COMMANDS
[None] Launches the simulator interface with a default scene create filename Creates a new empty scene and launches the simulator interface run filename Runs a simulation without loading the simulator interface exec filename Runs the given Python script with a default scene check Checks the environment is correctly setup to run morse help Displays information regarding the program version Displays the version number SEE ALSO
