Trying to create a macro that prompts the user to open a txt file.

FileName = InputBox("Please enter the Text File's name, e.g. test.txt")
FileNum = FreeFile()
Open FileName For Input As #FileNum

But in place of having them enter the file name, I want to have them browse
for the file then select it. This would be identical to File - Open, and the
Open Browser window appears.

Thanks
