Question about missionCommands.removeItem

[MagicRiggs]

Good day to everyone.
Please help me understand what I'm missing when working with functions for creating and deleting menu items.
Trigger "Mission Start", I set the action "Run script". Using a script, I create a couple of items in the F10 menu, and also put sub-items in them.

local A = missionCommands.addSubMenu('Columns')
 local A1 = missionCommands.addCommand('One column', A,function() trigger.action.setUserFlag('C1',1) end)
 local A2 = missionCommands.addCommand('Two columns', A,function() trigger.action.setUserFlag('C1',2) end)
local B = missionCommands.addSubMenu('Combat missions')
 local B1 = missionCommands.addCommand('Mission 1', B,function() trigger.action.setUserFlag('M1',1) end)

The menu is created as intended. When the conditions are met, the subparagraphs of the first paragraph are deleted by the functions below, but the subparagraph of the second paragraph is not deleted...

missionCommands.removeItem({['A'] = 'Columns', ['A1'] = 'One column'})
missionCommands.removeItem({['A'] = 'Columns', ['A2'] = 'Two columns'})

missionCommands.removeItem({['B'] = 'Combat missions', ['B1'] = 'Mission 1'})

The tables you are passing it aren't valid, but also aren't nil. The tables stored within A1 and A2 for example are actually this: 

{ [1] = "Columns", [2] = "One column", }
{ [1] = "Columns", [2] = "Two columns", }

However if you wanted to remove both of those at the same time you could just pass missionCommands.removeItem({[1]  =  "Columns"}) or effectively what is stored in A if you save that variable somewhere.

Thx Grimes. Understood. It works.
Can you explain how to correctly set the values of the variables in letters (A, A1, A2, B, B1), so that later I can use them to delete sub-items and the items themselves in my case?

Say you have a table that is global you can assign table entries as what gets returned by adding a command. 

 

table = {}
table["Columns"] =  missionCommands.addSubMenu('Columns')
table["One column"] =  missionCommands.addCommand('One column', A,function() trigger.action.setUserFlag('C1',1) end)
table["Two columns"] = missionCommands.addCommand('Two columns', A,function() trigger.action.setUserFlag('C1',2) end)
table["Combat missions"] =  missionCommands.addSubMenu('Combat missions')
table["Mission 1"] =  missionCommands.addCommand('Mission 1', B,function() trigger.action.setUserFlag('M1',1) end)

You could then call a given table entry when removing the menu you want. 

missionCommands.removeItem(table["Columns"])
table["Columns"] = nil -- best to delete it

Thanks a lot for your help with my question. 
I think that this example will be useful not only to me.
