Array & hotspots menu

[gaba]

I am creating an algorithm for graphically adding/subtracting elements of an array (dim_xy[ ][ ]) using hotspots (from the hot_mnu[ ] array).
It seems to me that adding new elements to the dim_xy[ ][ ] array works OK:

😊

But removing elements from the dim_xy[ ][ ] array unfortunately does not work properly because the last removed element of the array is restored:

😕😕😕

I noticed that for removing an element from the dim_xy[ ][ ] array to work, I have to click a hotspot not related to the hotspots hot_mnu[ ] before removing, i.e. remove in two stages:

😎😕

 

Where is the error? Can someone help?
I am attaching HotspotMenuGsm.zip (Ac27)

You can not remove the edited parameter.

Rather add one array element more than needeed and do not use it.
