X Problem

I have several asp labels that I'm putting sql table values into. The field is 10 characters long max and is varchar type. I know for a fact the data is varchar and it's value is not X, and it's never null. A typical value for this field would be something like: 4"W 2"T  Could the quotations cause this problem? For some reason the value that gets returned is "X" instead of the size field in my table. I'm scratching my head on this. I can only assume the X represents an issue converting the data or maybe it doesn't fit in the provided cell space? I did try making the label width wider and it didn't change. I even changed the label name to be sure it wasn't a mishandling of the label. This is the line in question:

   lblList1.Text = "Size: " + sqlRdr.GetValue(18);
When the data is returned it will display this regardless what the value is:  Size: X
I tried sqlRdr.GetValue(18).ToString; just to make sure if there were odd values that it will still be string format. Anyone else know how an X could be returned?
