Please fix my MIPS program:

$.$data

msg$\_$welcome: $.$asciiz "Welcome to main menu"

msg$\_$choice: $.$asciiz "Enter $1$ to compute the series

Enter $2$ to deal with array

Enter $0$ to end the program"

msg$\_$sub$\_$choice: $.$asciiz "Enter $1$ to add an element to the array

Enter $2$ to display the array elements

Enter $3$ to return to the main menu"

msg$\_$array$\_$empty: $.$asciiz "Array is empty"

msg$\_$end$\_$series: $.$asciiz "Enter the end of series: $"$

msg$\_$enter$\_$value: $.$asciiz "Enter the value: $"$

msg$\_$sum$\_$is: $.$asciiz "Sum is: $"$

msg$\_$exit: $.$asciiz "Exiting the program."

The two errors that i got:

rror in line $122$ column $5$: $"$li$.$s$"$ is not a recognized operator

Error in line $127$ column $14$: $"$$f$12"$: operand is of incorrect type

Assemble: operation completed with errors.
