That's what I needed. It is a customized field that I created as an integer. If I want to change it to decimal now, do I go to Tables/Fields> Edit Fields for the Invoice table (which is where the field is located). Am I supposed to be able to edit this field from there? I can see the list of fields including the custom ones we created, but no link to edit. I'm pretty sure I've done a similar edit before, I just can't recall where exactly I'm supposed to make these changes.
