How to turn predefined values for inputdlg function into a cell array or character vector

Hi all,

I would like to create an input dialog box with several parameters value to fulfill from the user. The pinions.txt file contains a list of these parameters, and a customer as first column, structured this way :

Customers,param1,param2,param3

CustomerA,valueA1,valueA2,valueA3

CustomerB,valueB1,valueB2,valueB3

I created a table out of this .txt file. I setted definput to already put the predefined parameters according to which customer is pre-selected in the listdlg function and not manually write them each time. These predefined parameters are located in the table in the row 'indx', which refers to the customer selected, and columns 2 to 9.

However, I don't know how to turn this piece of table definput to be a cell array or a character vector as requested.

Written this way, I get this error :

definput= Pinions{indx,[2:9]}
answer = inputdlg(prompt,title,dims,definput);

Error using inputdlg (line 112)

Default Answer must be a cell array of character vectors.

Here is the part of the code below :

Pinions = readtable('Pinions.txt')
%% Geometric variables definition 
Appli = string(Pinions.Application);
width=width(Pinions)-1;
Variables = string(Pinions.Properties.VariableNames);

% Enter customer variables (involute serration data).
[indx,tf] = listdlg('PromptString','Select a customer reference :','SelectionMode','single','ListString',Appli);

if tf==0
    msgbox('No application selected')
    return
end

input_check = 0;

    while input_check == 0
     for i=1:width
        prompt(i) = {Variables(i+1)};
        title = 'Geometric variables definition';                                                
        dims=[1 40] ;
     end
    
        definput= Pinions{indx,[2:9]}'
        
        answer = inputdlg(prompt,title,dims,definput);
       

Does anyone have a clue about this ? I hope to have been as clear as possible

Thanks !
