Is there a way to disable the blue triangle warning tag?

Question

I created a formula to generate dates a week apart (see screen grab below).  It works, but in most months, I get a blue triangle error tag stating that the day was greater than 31.  This happens when the previous date was the 25th of the month or later and the intermediate calculation generates a day of 32 or above, even though the displayed date does increment the month and display the correct single digit day. 
I know I can manually sellect each blue triangle individually and "ignore" it, but the more dates I generate the more blue triangle warnings I get.
It there a way to programatically / automatically not display blue triangle warning tags in a select set of cells?
or
Is there a better formula that I can use to generate dates a week apart that will not generate blue triangle warnings?

Answer 1

Warning triangles: No way that I've found.
Incrementing dates: Method 1—use auto-fill.
First date in A2, Second date in A3.
Select both cells, then drag the Fill control down the column. Dates will increment according the difference between the two starting dates.
Incrementing dates: Method 2—use a simple formula:
First date in A2.
In A3: =A2+7
Select A3 to the bottom of the column (see note below)
Go Insert > Fill > Fill down.
Done.

NOTE: re selecting;
Click any cell to make the table active and show the row and column reference tabs.
Click the reference tabe for column A to select the entire column.
Command click A1, then A2 to remove these two from the selection.
NOTE 2: The information here is also readily accessible in the Numbers '09 User Guide, an easily read pdf file well worth spending an hour or two browsing. The guide may be downloaded via the Help menu in Numbers.
