Error saving to variable in load

If you're going to be having users or on-form actions do manual updates to the value of a local variable, the variable should in fact be declared as a load() variable. It of course requires a somewhat different design approach to with() variables which are updated 'live', but strictly automatically and in accordance with the initial definition.

In your case, if you need the variable to be updated whenever (for example) the user interacts with a grid, then you will want to use a!save() in the saveInto section of the grid to set whatever value is necessary. Likewise with any other fields on the form that would cause its value to update when interacted with.

So the action in the grid that updates the variable is actually a row selection of the grid using the left hand checkboxes. This is why I'm doing the with of the variable which captures that user interaction with the form.

I understand, but like I said, you'll need to refactor a bit, so as to do the update of your local variable manually within the saveInto of your grid in order to get the other functionality you've described working.
