Tab control problems

[detech]

I made a peogram to look at the file name back and forth. seefile.vi works great. I also need to do further work after seefile.vi. I created TAB control with two pages. Simply I duplicated seefile.vi (page 1) as page 2, which is seefile1.vi as attached. Now I can not run it right. The problem is Next Buttorn can be used once and then it is running for ever.
If I delete all content in page 2, it works great again. My question is what in page 2 can cause Next Button in page 1 frozen??? Or I did not figure TAB control right.

I don't see any Tab control, I don't see page 1 or page 2, I don't see a Next button, and I don't know what you're talking about. You will have to do a better job at explaining what it is that you want. Also, in one of your block diagrams, you have a loop condition with a False wired to the Stop sign. This will cause your vi to run forever.

I am sorry I attached wrong vis. I will post my question again.
