First, note that RabbitWeb makes use of single-letter variable names for loop control. You should be using multi-letter variable names in your program.
Second, RabbitWeb does not support multiple levels of array indexing. You can work around this by using a loop:
int foo[3] = {11, 22, 33};
#web foo
int bar[3] = {1, 2, 3};
#web bar
shows "1"
shows "22"
shows "22"
It’s a bit of a hack, but it accomplishes your goal.
Finally, please use the latest version of Dynamic C (10.72A). You can view the Release Notes for an idea of how many bugs have been fixed since the 10.66 release you’re using. There’s also a 10.72B release in the works – you can see what’s going into that on the GitHub repository for Dynamic C.
