I have a pet project of mine that I'm working on; basically, it's for scouts during FIRST FRC matches and allows them to enter data about teams into an Excel sheet. I'm having a problem creating said sheet, however. I want the program to create a new sheet, with the filename being whatever the user puts in a textbox I have. the interface takes data about teams one team at a time; when user wants to add a new team, they press "Enter Data" (which puts whatever is in the interface on Row x, then the user will be able to add new data to Row x+1 each time they press said button, etc). The main issue is that when I have the code as follows:

I've narrowed the problem to the "filename" and "filepath" variables. I've Googled around for answers, but the articles that I found about the error above are too vague to help me. Does anyone know why VB.NET is giving me this error? Also, how can I reuse the same Excel sheet for the entire duration that my VB.NET application is running? As in, I want to be able to add ~50 or so teams to the same Excel document (for example, all of it going into "MyRegional.xls").
Sorry if this is an obvious problem to solve or anything; I'm fairly new to programming in general, so I'm clueless as to what's going on with this. Up until this point, my program runs fine and when I comment out "Dim filename..." and "Dim filepath...", the program will run normally. If it helps, I'm running VB.NET Express 2010 in Windows 7 Home.
