How can I get the research slots in use?

[Artajörn]

Hi,

I'm trying to get the number of free research slots. To do that, I'm using the following code:

local currentSimultaneousResearches = 0
local researchLines = {}
	
for index = 1, GetNumSmithingResearchLines(CRAFTING_TYPE_BLACKSMITHING), 1 do
	researchLines[index] = GetSmithingResearchLineInfo(CRAFTING_TYPE_BLACKSMITHING, index)
		
	if researchLines[index].timeRequiredForNextResearchSecs > 0 then
		currentSimultaneousResearches = currentSimultaneousResearches + 1
	end
end

It seems not work, so I must be doing something wrong. Can you help me, please?

Regards and thanks in advance.
