The No-VBA way
There’s nothing wrong with this method in and of itself, but I want to propose a method that requires no VBA. The advantage of this new method is that it links directly to the data itself and bypasses the need for the Linked Values table. We can do this by allowing the form controls to take advantage of dynamic references.
Typically, form controls can only do direct, absolute references. You cannot, for example, use VLOOKUP or INDEX within the source field of a form control. However, you can use a named ranges.
Let’s do it!
First, we give that ‘index’ field above a named. How about selection? Next, we create four named ranges to correspond to the form control checkboxes. Stage_1 to Stage_4 are those new named ranges.
As you can see from the picture, I use the fourth row to connect to checkbox Stage 4 and the selection value to inform Excel to pull from the fourth column in the backend data (which is Project 4, if you recall).
Finally, I can simply link these named ranges to their associated checkboxes:
Using this method, changes to the checkbox automatically change the backend data. There is no intermediate table required — like the Linked Values table above — to interface between the frontend and the backend.
That’s all for now – have a happy and health holiday season!
