How do you save an input field with a blank value?

I have a simple workflow that runs on an inpux field on a form that says if the field is modified, update the current page’s record field value with the value of this input box. This works perfectly fine, however if I clear the input box to make it blank, it won’t save.

Why is that, and how do you code it so that users can actually erase the value of a field and have it save?

Are you saving other values at the same time or just this one field?

It’s just this one field. I have a workflow that runs on every field whenever they are modified, which just updates the database field value with the value from the input box. Has worked forever but just today when trying to make something blank I realized it doesn’t save unless there’s a value in there. It’s not often I’d have a need to save a field blank but just confused why it would do that.

did you figure it out? I am trying to save a data field in blank
