sw $rs, imm($rx) (store word)

[mayio]

Hi to you all...!
I am new to assembly, and I have a small problem with sw(store)
I can't figure how is the proper use of this instruction. I want to store the integer I've read to an array of integers.
My code follows, I get an 'Exception 7 [Bad data address] occured and ignored' in sw $19, 16($10) # STORES
How should I declare sw(at the end of the code)???

thank you in advance!

         # register $7 : .,.,.,.,
        # register $16: Array Start Address
        # register $17: i
        # register $18: j
        # register $19: tmp
        # register $20: tmp2
        # register $26: 8, The number of the values
        # register $27: 1
        # register $28: x

    .data
    .align 2
    Array1: .space 32 #Array1 can store 8 integers(each 4 bytes)
