Correct and expected behaviour.

It does, which is the problem.  It understands that thisLine is an array of the
dimensions that you specified, and you're supplying too few inices for it to
locate the element[s] that you want.

You totally can, I do it all the time.

Hard to understand exactly what you mean, but:
All you do is pass the FULL array into the macro and then define the way you
address the parts of the array that you want to access.

If you only want to access the second dimension, then just hold the first one
constant, but you do have to put that into your ArrayName [index1][index2]
designation.

This I think would also be a way to avoid the error, and might be better, as you
can then have a parent array that is composed of sub-arrays of _different data
types_.    :)
