Hi, i have 2 functions where i calculated a variable in function 1, now i want to use the variable in function 2 but it says variable not recognised. In my case i calculated TableFiles(which has names of excel spreadsheets) in function 1 and i want to open the files in function 2 using read cell. Please help

    function [LookupTableFiles]=getaerotablelisting( FilePrefix, DirectoryName , filetype )
        FileList = dir('DynamicData*.xlsx')
        TableFiles = {};
         for LenFlLst = 1:numel(FileList)
             TableFiles = {FileList.name}
         end
    end
    
    function [Cols,StructOut]=getindepvars( CurrentSheet )
        
       for LenTables = 1:size(CurrentSheet)
           CurrentSheet = readcell(TableFiles);
           Raw = CurrentSheet;
           if ischar(Raw{1,1}) == 1
              IndepVariablename = Raw(1,1);
              Range = Raw(2:end,1);
              StructOut.(Raw{1,1}) = [Range{:}];
              a = size(Raw);
              Cols = a(:,2);
           end
       end
    end

Pass it in when you call the second function:

function LookupTableFiles = getaerotablelisting( FilePrefix, DirectoryName , filetype )
FileList = dir('DynamicData*.xlsx')
LookupTableFiles = {FileList.name}
end
function [Cols,StructOut]=getindepvars( CurrentSheet, LookupTableFiles )
for LenTables = 1:size(CurrentSheet)
	CurrentSheet = LookupTableFiles{LenTables};
	Raw = CurrentSheet;
	if ischar(Raw{1,1}) == 1
		IndepVariablename = Raw(1,1);
		Range = Raw(2:end,1);
		StructOut.(Raw{1,1}) = [Range{:}];
		a = size(Raw);
		Cols = a(:,2);
	end
end
end

Lots of other problems with that code but I don't have time now to fix them all....sorry
