Have a column with a drop down table. The drop down when I look at data validation and the source shows a range in another sheets column(I will call column B. The range in column B is hard coded. When I update the hard coded name in Column B I should see the updated name in the drop down. The drop down is definetly populated by column B but I dont understand why when updating column B the changes are not reflected in the drop down??? Any ideas???

How exactly is the range set in the dropdown?

Is it a named range or a reference like Sheet2!A1:A10?

Is calculation set to Automatic?

My guess is the drop down is dependent upon a range (like Norie mentions).  If the range was Sheet1!B1:B10, you would most likely need to increase the range to include the new item.  Something like Sheet1!B1:B11,

Hi there! :)

Replace your source destination in the data validation with this. In the formula, B2 is the first cell of the data range you want to create a drop down list with, and B:B is the column original data located at.

=OFFSET($B$2,0,0,COUNTA(B:B)-1)

When looking in the source says Bin1 then jumps to a range that is with dots around it. I am updating not adding rows. Example the drop down currently contains John in the cell. I update the source to John Wayne and would like to see that reflected in the drop down. Instead I still see John, I hope i dont have to add a new row with John Wayne to see in the drop donw? Thanks in advance

Wait, have you tried the formula I gave above? If so, like @Norie mentioned, please set your calculation set to Automatic.

It would quicken things if you uploaded a sample file showing your problem. You can fake the relevant data and delete the rest.

Using your John Wayne example,

If you have previously selected John from the drop-down and then changed the entry in the source list from John to John Wayne you will need to reselect John Wayne from the drop-down, it will not change automatically.

I have included the file. I would like (maybe not possible) to go into the resource tab  - edit the row which I can do. Then go into the lava tab go into the individual cells I used as an example LaMotta PT Large Displ's LaMotta (975,1250). So I would change source to LaMotta PT Large Displ's LaMotta (975,1250) test then go into the lava tab and then see my changes in the fit_eng tab. As you can see it will not change unless I go into the lava chart go into the cell and choose it from the drop down. CAn I automatically update these cells without pulling them in from drop down. Hope I explained what I am trying to do. Thanks in advance for helping

As mentioned earlier, the previous choice from a validation list will not change if the source list is changed, not automatically anyway. It would have to be a VBA routine which is triggered when the source list is changed and then checks the previous choice to see if the item in the amended source was previously in the validation cell.
... and then see my changes in the fit_eng tab. As you can see it will not change unless I go into the lava chart go into the cell and choose it from the drop down....
This is how this data validation works. You have to choose it again from the dropdown.


CAn I automatically update these cells without pulling them in from drop down.
Will try and see if this can be worked out. Maybe someone else can find a way.
