I want when index increase no. of layers should give inf or button disable to not accept more inputs,thanks

function ButtonPushed(app, event)

L = app.nooflayerEditField.Value;
r = zeros(L,1);
for i=1:L
    if i > L
        app.Button.Enable = off;  
        app.firstValEditField.Value= inf;
    end  
    app.Button.Enable ='Off';
    waitfor(app.firstValEditField.Value);
    r = app.firstValEditField.Value;
    r(i) = r;
    app.Button.Enable ='On'; 
end     
disp(r(i))

for i=1:L
    if i > L
        app.Button.Enable = off;  
        app.firstValEditField.Value= inf;
    end  

When you have for i=1:L it is not possible for i to exceed L (unless you specifically assign to i). So it is not possible for the test if i > L to succeed.

    app.Button.Enable ='Off';

If the test somehow did succeed, then the first thing you would do after the if block would be to set app.Button.Enable back to 'off', which is a bit pointless.

    waitfor(app.firstValEditField.Value);

app.firstValEditField.Value is a numeric value. You cannot waitfor() a numeric value.

If you wanted to wait until app.firstValEditField is deleted, you would

    waitfor(app.firstValEditField);

If you wanted to wait until app.firstValEditField.Value changed then you would

     waitfor(app.firstValEditField, 'Value');

A problem with waiting for it to change is that if user wants to retain the current value, there is no way to do that.

I will try itthanks a lot

[m.montaser sabry]

It does not work

and to prove i send the try , you can try.

thanks again\

L = app.nooflayerEditField.Value;
r = zeros(L,1);
for i=1:L
    if i > L
        app.Button.Enable ='off';
    end 
    app.Button.Enable ='Off';
    waitfor(app.firstValEditField.Value);
    
    r(i) = app.firstValEditField.Value;
    
    app.Button.Enable ='On'; 
    app.secondEditField.Value =  r(i);
end     

[Walter Roberson]

Again, when you have for i=1:L it is impossible for i > L (unless you assign to i inside the loop.)

Again, waitfor(app.firstValEditField.Value) is requesting to wait on a numeric value, which is not possible. I already discussed your correction options.

[Walter Roberson]

L = app.nooflayerEditField.Value;
r = zeros(L,1);
for i=1:L
    app.Button.Enable ='Off';
    app.firstValEditField.Value = inf;
    waitfor(app.firstValEditField, 'Value');
    
    r(i) = app.firstValEditField.Value;
    
    app.Button.Enable ='On'; 
    app.secondEditField.Value =  r(i);
end

Thanks for you So how can I over on that problem Thanks in advance

[Walter Roberson]

I think the code I posted should work.

[m.montaser sabry]

With regret does not work anyway many thanks for you.
