Array of Strings MIPS - string

Question

So my program is running into an infinite loop when printing words:
It's printing the first character of my array, but it's not incrementing to the next character. I'm not sure what exactly to do at this point: adding i * 4 + 1 ran into an exception and i * 4 only prints the first character. Suggestions?
#Prints original string
#Prints each word in string
#Prints word count for each string
#Prints final concatenated word count
.data
phrases: .word string1
.word string2
.word string3
.word string4
.word string5
.word string6
.word string7
.word string8
.word string9
.word string10
.word string11
.word string12
numPhrases:
.word 12
string1: .asciiz "Four-score"
string2: .asciiz "and seven years"
string3: .asciiz "ago, our"
string4: .asciiz "fathers"
string5: .asciiz "brought forth on"
string6: .asciiz "this continent a"
string7: .asciiz "new nation, "
string8: .asciiz "conceived in liberty"
string9: .asciiz "and dedicated to the"
string10: .asciiz "proposition"
string11: .asciiz "that all men are"
string12: .asciiz "created equal."
