I tried to use the App tool - the drop down menu. I asked for the .Value in the code view and printed it in the Command line. All that was fine. However when I tried to route the execution using the value: if val == 'name' where name was the value I got errors. I thought the value was a text string, so I do not see how that causes an error. Can you tell me how to use the drop down menu Value properly? I looked in the documentation, but could not find an example of using the drop down. Thanks, in advance.

To compare strings, use strcmp(), strcmpi(), or contains() depending on how you want to do the comparison. If you use == it will give you an array of true or false values for whether each character matches or not then you'd have to use all() to see if they all match. Plus that doesn't work if they have different lengths. It's better to use strcmpi()

theyMatch = strcmpi(val, name);
