Can This Work?

Can someone please tell me why this application doesnt work after endless hours spent on it. I built it with the help from this site and the code used is in response to specific questions about each part of the proecure. God knows how many times I've pasted my whole code on the site only to be given a link to something that tells me how to create what I allready have. Its getn boring and I only do this for fun. You helped me make the error pop ups stop during run time but the application is useless and I dont know what I've done wrong.

The first issue for me is the form load procedure. From the start I contained a file name which always opens succesfully but many times I'v asked for the top file in the MRU list to be the file opened automatically on loading and I was told that what I have should do that! I can see how.

The second issue once the form load is fixed is the fact that when I open a file data is shown in my text box. I've never wrote code to make anything show in a text box so I dont understand why this is happened and cant see the code that makes it happen. The text box only allows 3 digits so compared to the large list of information on the file its a small amount of data.

If someone can explain to me why these problems are happening and help me fix em step by step that would be great. I'll raise the points the longer it takes.

One piece of code I was given on here is this...
On Error GoTo FileLoadError
fnum = FreeFile 'Allow multiple files to be opened without declaring them each a number.
Open file_name For Input As fnum
txtReps.Text = Input$(LOF(fnum), #fnum)
Close #fnum

I DONT understand why it mentions txtReps.Text at all. This is meant to be for opening a file and the text box was created to submit information to the list1 box.
