A solution to what? Maybe make the effort to actually explain the issue. If you're using an older version of VB that doesn't support string interpolation then either update to a newer version, e.g. 2019, or just don't use string interpolation. There are other ways to construct a String from parts and we shouldn't have to explain then to you. If the problem is something else then I have no idea what it might be, which is why you need to explain it.
