These are operations that Excel will not let you do. Some are not allowed through the rules of mathematics. A typical example is trying to divide something by zero. That is a mathematical impossibility, and so in Excel it is treated as an invalid operation.
#NULL!
IZ10 would be an invalid address in version 2003 of Excel and earlier versions. The last column in Excel 2003 is column IV, so there is no column IZ. In versions from Excel 2007 onwards, IZ10 would be a valid cell address.
true
An invalid clip operation, when it comes to a Nokia 5800, means the format is not supported. An invalid clip operation can also occur in Excel which means the code you're using is incorrect.
No it is not invalid. It is the cell address of the cell where column B meets row 17. It is a relative cell address.
If there is an invalid cell reference you will see #REF! in the cell. If you refer to a defined range name that does not exist or a function name that does not exist you will see the #NAME! error.
cell protection
Cell protection only kicks in when you protect the entire sheet. So for the cell to be protected, then the sheet has to be protected.
