Fill array with data using Load from JSON string.

I have found a weird problem and i was hoping that somebody would be able to help me. The problem is that when i try to load (be it a variable or AJAX) requested data into an array it does not fill an array with data. Though when i simply put the json string into the Load from JSON string it works fine.

I have been searching around and found one other person with a similar problem to mine but there was no answer to his/her question really.

JSON code:

"{
""c2array"":true,
""size"":[21,1,4],
""data"":[
[[8,1,0,330]],
[[10,2,1,110]],
[[12,3,2,220]],
[[14,4,1,110]],
[[16,1,0,330]],
[[18,2,1,220]],
[[20,3,1,110]],
[[22,4,0,330]],
[[24,1,1,110]],
[[26,1,0,220]],
[[28,2,1,110]],
[[30,2,0,160]],
[[32,3,0,330]],
[[34,3,1,180]],
[[36,4,0,110]],
[[38,4,1,250]],
[[40,3,1,110]],
[[42,2,0,290]],
[[44,1,1,330]],
[[46,3,0,110]],
[[48,2,2,170]]
]
}"

You don't need the extra quotation marks if you're storing it in a variable or in a file.

Ah thank you always the small little things :D
