Use Of Square Brackets In Vba 2003

My code works great on my computer but when I bring it to another computer it gives me errors. I think it has to do with my use of square brackets to reference cells. the error that comes up is

compile error:
can't find project or library

What I'm doin here is going to my template sheet then getting the info from different cells and then later using it somewhere else. in place of using range and selecting cell I am using square brackets to select a cell. it worked fine on my computer and was a lot less writing, here is a small part of my code
