MATLAB app designer, Reading in arrays

Hi Everyone,

I am trying to read in arrays(eg,[1,2,3,4]) from a text edit field and convert it to a numerical value and perform mathematical operations to get a value. However, I am getting an error

'Value' must be a double scalar within the range of 'Limits'. Could someone assist please?

Thank you,

Tyler Seudath.

x=str2double(app.timedelay.Value);
y =str2double(app.Relativepower.Value);
%mean excess delay
numerical_value = (10.^(y./10));
a= numerical_value.* x;
mean_excess_delay= (a.*x)/sum(numerical_value);
app.aEditField.Value =mean_excess_delay;
