Experts,
In my spreadsheet I use the following ranges for a specific purpose:
A12:A21 - Date Entered
F12:F21 - Invoice Date
G12:G21 - Invoice Amount

I would like to keep data from being entered in F12:F21 and G12:G21 unless there is a date in the corresponding range A:12:A21

To have conditional locking / unlocking of cells, you'll need to use VBA.

Here's an example that should be able to be adapted to your needs:

Hope this is a good start and helps you out.

You don't need VBA. Select cell F12. Navigate to tab Data. Click "Data Validation" in the "Data Tools" group.

Select "Custom" and enter this formula:

   =AND($A12>=DATE(2000,1,1),$A12<=DATE(2099,12,31))

Copy the formatting in cell F12 to the other cells.

I agree, that's a much better solution.

You can restrict the range of dates that must be entered in column A. For example, to restrict the dates to today to 31 days from today:

   =AND(A1>=TODAY(),A1<=TODAY()+31)

Select cell G12. Navigate to tab Data. Click "Data Validation" in the "Data Tools" group.

Select "Custom" and enter this formula:

   =AND($A12>=DATE(2000,1,1),$A12<=DATE(2099,12,31),$F12>=DATE(2000,1,1),$F12<=DATE(2099,12,31))

Copy the formatting in cell G12 to the other cells.

I entered in the formula in G12 for data validation, entered in valid dates in A12 and F12 and an amount in G12 and I was kept from putting in an amount - it did not work.

I also have a conditional formatting that also applies to G12 - could that be the problem

That should not interfere.

Can you post your workbook? If not, try to reproduce in another workbook with dummy data and, if the problem still exists, post that workbook.

Also, I forgot to mention that your must uncheck the "Ignore blanks" checkbox.

unchecking the ignore blanks was the difference - great - I'll close this and open a continuation
