Iswar has two cells in which users enter degrees and minutes, which represent latitude. The values can necessarily vary from 0 degrees and 0 minutes to 90 degrees and 0 minutes. He wants to use data validation to check and limit what can be entered in the two cells. For the degrees Iswar can validate that the value is between 0 and 90. The problem is with the minutes cell, which can vary from 0 to 59 unless the degrees cell is 90, then the only acceptable value is 0 minutes. Iswar wonders how he can create the validation for the minutes cell to take this into account.
Assuming that you enter degrees into cell A1, you could set up validation for the degrees in this manner:
Figure 1. The Settings tab of the Data Validation dialog box.
Now, assuming that you enter minutes into cell B1, you could set up validation for the minutes in this manner:
The formula used for the Maximum value (step 6) sets a maximum for the cell based on whatever is entered into cell A1 (the degrees).

Using this setup, if you enter a value less than 90 into A1 and then a valid non-zero value in B1, that works as intended.
But it is still possible to then go back and change A1 to read 90 while B1 is greater than zero. In that fashion you can wind up with say, 90 degrees and 54 minutes.
