Conditional formatting doesn't update when I delete a row

Question

So I have a sheet which has a conditional format something like:

=$R1<>$R2   

Which applies to the entire range of A1:C1000.

Now let's say I have the cells:

R09 = "ha" 
R10 = "ha" 
R11 = "hi" 

Which means the condition is true and the entire row will be formatted. So it does and it all works great.

But now the problem arises when I delete row R10 then the conditional all gets broken and doesn't do anything. It still does work for other rows but the new row R10 with value "hi" doesn't get formatted anymore. (Deleting other rows where the value is the same gives no problems. Adding rows neither) When I look at the formula it says

=#REF!<>$R11 

Now I already tried pressing F9 and made sure that events are enabled. I also tried to use INDIRECT

=INDIRECT($R10)<>INDIRECT($R11) 

But that didn't work at all.

How should I proceed? I can't impossible keep changing the rownumbers?

Answer 1

Try:

=OFFSET(A1,0,0)<>OFFSET(A1,-1,0)

This will look a row above the current row for the comparison. I would think this is deletion resistant.
