Hi

Can anyone look at the code below and explain why it works sometimes and not others?  
strSl\_Title is taken from an array and the whole process is in a loop.

```auto

if (strSl_Title.length>31) {
        myString = strSl_Title.substr(0 , 28) ;
        strSl_Title = ""+myString+"...";
    }

```

It appears to be something to do with spaces in the string but I ain’t sure?
