Function is throwing error when calling it in different script

I have a function, attached, that I am calling in different script. Everytime I call it I get the error

"Local function name must be different from the script name"

I was under the impression both the script and function must have the same name? Atleast how i have my other functions working. Nonetheless, even when I resave it with a different name I cant get it to work

You have a non-comment line before the function definition starts. Thus, Matlab thinks that this is a script. Make the first line a comment, and this problem should go away. Note that the code analyzer in the editor flags this issue with red squiggles under the function name and also flags some other issues with orange squiggles. You need to fix those as well. Specifically, you can't use == to compare a character vector. You either need to use a string scalar (with double quotes, if the Master parameter that you pass in is also a string scalar) or use the strcmp function.

function  [wl,Deg] = GtDis2wL(Master,Dist,Peak)







    if Master == '2135'
    
        rExt=100;
        alpha=2.627499; %deg
        beta405=-32.0725; %deg
        WL=6010; %nm
        G=1197.9*10^-6; %g/nm
        names=-1;
        DistOfst=Peak-Dist;
        DegOfst=atand(DistOfst/rExt);%deg
        Deg=DegOfst+beta405;%deg
        
        wl=(-1/G)*(sind(alpha)+sind(Deg));
   
    else
        print('Hello')
    end 

end
