I'm attempting to pass a variable into the following function;

function Test_Message_Body_Builder(BLength)
f = figure('Name', 'Message Builder', 'numbertitle', 'off', 'Position', [100 100 1450 700], 'resize', 'off');
t = uitable('Parent', f, 'Position', [25 25 840 300]);
DefaultData = {'Fmt:' '19 (PLAYBACK)' 'Length:' BLength 'Remote Num:' 0 ' '  ' '  ' ' ' '};
    set(t, 'Data', DefaultData);
    set(t, 'ColumnFormat', char);
    set(t, 'ColumnWidth', {160, 160, 160, 160, 160, 160, 160, 160, 160, 160});
    set(t, 'RowName', []);
    set(t, 'Position', [0 0 1450 700]);
    foregroundColor = [1 1 1];
    set(t, 'ForegroundColor', foregroundColor);
    backgroundColor = [.4 .1 .1; .1 .1 .4];
    set(t, 'BackgroundColor', backgroundColor);
    set(t, 'ColumnEditable', [true true true true true true true true true true]);
    set(t, 'ColumnFormat', {[] []});
    set(t, 'CellEditCallBack', @ValueChange);
    % Assign default ComplexData to the base Work Space
    assignin('base', 'Default_Message_Body_Values', DefaultData);
    end

Where the variable, BLength, is a 1 x 1 double. Once executed, the table displays a default set of values/characters which can be edited by the user during testing.

However, when I try to run the function, I get the following error;

>> BLength = 704;

>> run Test_Message_Body_Builder

Error using Test_Message_Body_Builder (line 4)

Not enough input arguments.

where line 4 begins with DefaultData = ......................

This is the first time I've tried passing a variable to a cell array within a function.

Any thoughts are greatly appreciated.

Thanks.
