Please describe the problem:
When the options for 'First round #' and 'Last round #' are entered, the first round number should be less than or equal to 'Last round #'.  If not, a warning message appears stating "First round number should be greater or equal than the number of the last round."
The error message is incorrect.  It should be
"First round number should be less than or equal to the number of the last round."

Steps to reproduce:
1. Set A1 to rand()
2. Select Tools -> Simulation
3. For Simulation Variables, set Input to Sheet1!A1 and Output to Sheet1!A1
4. For Simulation Options, set First round # to '2' and 'Last round #' to 1
5. Click 'Ok'


Actual results:
Warning dialog box appears stating "First round number should be greater or equal than the number of the last round."

Expected results:
Warning dialog box appears stating "First round number should be less than or equal to the number of the last round."

Does this happen every time?
Yes
