How To Reset The Formulas To The Original Values

I expressed the node values as variables to keep the curve fixed along grading.

Now I want to revert to the original values to calculate again.

When I delete the formula It gives Length : Error

How can I do this?

I had clicked Save button.

Then I think It cannot undo on this app?

I thought maybe It keep the original formulas of the nodes?

Not once you save. Other than if your autosave time is fairly long and you’re able to copy the autosave file before it’s over written.
