When you ask questions, try to be as precise as possible. "I have issues" is very vague. I suppose it means "this still isn't working," so you should say so.

When you ask if the word "blank" should be in the quotes instead of "indt" you might as well tell us if you tried it that way.

No, indt should go away and "" should remain.

To confirm that the files are executable you could type

ls -l

Those are ls as in lemon and they stand for long, meaning give us lots of information.

They should show us some xs for executable in some places.

You could show us what you have rather than just asking questions.
