Change value of existing row and column in datatable

[Aarron (Aaron)]

I want to change the value of each row in column “URL” but I got this error. The message box before the error node worked fine as expected. What is this error? How can I fix it?

I found the error. Apparently, the assign activity was row.Item(“URL”) = “url” + row.Item("URL).ToString
I removed + row.Item(“URL”).ToString and the error was gone.
So I assign a string str = “url” + row.Item(“URL”).ToString then assign row.Item(“URL”) = str
I still don’t know why the error happened in the first place.
