Whenever I run my function to load a name and return an excel file for that name, I get this error:
Error using xlsread (line 122) Filename must be a string.
Error in loadNCIR (line 9) [~,vaccineName,~] = xlsread(excel);
function [Name] = loadName( Name )
excel = inputdlg(['Please enter the name for the ' Name ' xls file: ']...
,'s');
if strcmp(excel, '') == 1;
Name = {};
else
[~,Name,~] = xlsread(excel);
end
What am I doing wrong? My input is a variable for a string, and the output should be the excel file.

The inputdlg function returns a cell. Use char to convert it to a string variable:
excelstr = char(excel);
