I don't think error handling is necessary. You can use type() or vartype() first, to check whether _screen.Forms[lnCount] exists.

Error handling is more likely to be required to handle anything OUTSIDE your application, such as access to files - where you can't tell in advance what the situation is going to be (e.g., whether a file exists, or whether you can actually access it).
