Reading multiple editable text boxes and writing them into a single array

So for a project that I am doing that requires programmatic GUI development, I am trying to write a program that can read single letter inputs from multiple editable text boxes and put them into an array to be used later on. I found some code posted by Walter Roberson in 2013 that successfully created the boxes using a for loop, but I am running into errors with the part that compiles them into an array.

Here is the part that creates the text boxes:

np1 = 5;
editp1 = zeros(np1,1);
for K = 1:np1
  editp1(K) = uicontrol( 'Style', 'edit', 'Units', 'normalized', 'Position', [(0.1+((K-1)*0.04)) 0.7 0.04 0.07]);
end

and here is the part that is supposed to read the inputs and put them into an array:

p1vals = cell(np1,1);
for K = 1 : np1
  p1vals{1i} = get(editp1(K), 'String' );
end

When i run the code with these in place, it gives an error stating: "Array indices must be positive integers or logical values." and each cell just has "[]" in it.

For reference, I only need to read the inputs when i push a button on the GUI. Would the second block of code go in a callback function? And if so, what would that look like (on both the button's line of code and the callback function itself)

p1vals{K} = get(editp1(K), 'String' );

Why do you like to use complex variable,1i as cell array index, p1vals ?

Ok yeah that's my own fault, I'm very new to this and it's just leftover from what i copied over from the previous code. This got rid of the error, so thank you on that front.

However as to the second part of my question, How would I use this code to make it update the array p1vals when i push a button?

Thanks for the quick reply btw
