Strange Behaviours.....

Hi all,
My VB .NET is acting strangely. I have a code on a button click that calls a function openScore(). This function opens an excel file. I have another function by the name of openExcel() which I just added to the click of the same button and has to be executed before openScore(). My problem is that when i run this code, VB is skipping the new function I added (openExcel()) and is going directly to the openScore(). Also, I commented some lines, but they are being executed by VB. Can someone help me with this??? I don't know y this is happening.
