Dual Data Validation in Excel

Hi,

I want the user to input time in D12 in hh:mm 24hrs format only when cell D9 is not "--".

So, it's a dual validation:

  1. Entered time must be in hh:mm format (24 hrs)
  2. Cell D9 must not have "--".

Any help?

Select D12.

Format it as hh:mm

On the Data tab, select Data Validation.

Select Custom from the Allow drop-down list.

Enter the following formula in the Formula box:

=AND(ISNUMBER(D12), D12>=0, D12<1, D9<>"--")

If you wish, enter an instruction in the Input Message tab, and/or an appropriate error message in the Error Alert tab.

Click OK,
