This is exactly how the tutorial tells you to do it (even though this
isn't the question you had asked).

The easy to remember, basic rule from the tutorial: group with (*xxx)
all "xxx" which are pointers, unless the () would then occur on the
"outside" of the expression (it wouldn't hurt, it's just a waste).

So in your case the pointer "ptr_data" must be treated this way:

(*ptr_data)

as must the pointer "(*ptr_data)[3].level[3].grds":

(*(*ptr_data)[3].level[3].grds)[0,4]

if you didn't want to subscript the final FINDGEN, you could just use:

*(*ptr_data)[3].level[3].grds
