Thank you for the screenshot showing the input and the error message. That allows me to diagnose exactly what the problem is.
Look in your screenshot at the end of the fifth line. See that line ends with }, ,
That is a closing brace and two commas with no string between those commas.
Look at my previously posted solution which began with “Remove the extra comma you have between two strings in prb and then…”
Try doing that and my solution should then work.
If you cannot have a list of strings without extra commas then you may need to find a way to write a line of code to eliminate any Null items from your list of strings. Perhaps DeleteCases might help with that.
