Code not opening the workbook due to unknown reasons

I have the following piece of code, that is supposed to open one or another file depending on the value in a cell. The problem is that it returns an error saying that the file may have been moved or deleted. The file name is partial, but the error returns the full name of the workbook. Meaning that it finds it in the folder, as I can clearly see it. Any ideas why? Error line marked.

So stupid and so obvious. I removed the directory from the syntax without paying attention. Thank you for pointing it out.
