There are no silly questions to ask; And this forum is all about learning.
That being said, users need to realize that if you don't understand your entire system and how the applications integrate with one another, we can give a simple answer here which may cause 14 other things to break on your system.
That's when we get the call saying "this stopped working". It most likely didn't just "stop" working, most likely the end user modified something else and didn't realize that by making one change, it effected other things. There is no way on this forum that we would understand the entire architecture of your system and all the intentions of the original designer.
