I want to put fig files as subplots

I have four different .fig files, which I want to display in one figure with individual fig files as subplots. ALthough their xlimits are same, ylims are different.

Can you please figure out what is wrong with the following code?

h1 = openfig('PPT5.fig','reuse'); % open figure

ax1 = gca; % get handle to axes of figure

h2 = openfig('PPT14.fig','reuse');

ax2 = gca;

h3 = openfig('PPT2.fig','reuse'); % open figure

ax3 = gca; % get handle to axes of figure

h4 = openfig('ACC12.fig','reuse');

ax4 = gca;

% test1.fig and test2.fig are the names of the figure files which you would % like to copy into multiple subplots

h5 = figure; %create new figure

s1 = subplot(4,1,1); %create and get handle to the subplot axes

s2 = subplot(4,1,2);

s3 = subplot(4,1,3); %create and get handle to the subplot axes

s4 = subplot(4,1,4);

fig1 = get(ax1,'children'); %get handle to all the children in the figure

fig2 = get(ax2,'children');

fig3 = get(ax3,'children');

fig4 = get(ax4,'children');

copyobj(fig1,s1); %copy children to new parent axes i.e. the subplot axes

copyobj(fig2,s2);

copyobj(fig2,s3);

copyobj(fig2,s4);
