Hi guys,
I am running R2013a with Jsonlab plugin, and here is my problem:
I am creating a function which retrieves the value attached to a key inside a Json file. The inputs to my function are the Json file and the key, and the output should be the value (with a specific formatting)
But here is the thing: I usually access the value by writing " filename.key ", but since here the key is input as a string in the function, the program behaves as if I was calling " filename.'key' " and returns me the following error "Reference to non-existent field 'key' "
Any idea on how to go around this issue?

Ok, problem solved!
The trick is to add parenthesis around the key, like that:
"filename.(key)" instead of "filename.key"
Then it also works with "filename.('key')"
It might help someone else.
