Fill form does nothing on the page

The four reasons the button finds no target, in the order worth checking.

What you see

The panel shows the fields, Fill form is pressed, and nothing changes on the page.

Why it happens, and what fixes it

01

The accounting tab lost focus

Click once inside the expense form, then press Fill form again. The panel writes into the tab that was active last.

02

The form sits inside an iframe the extension may not touch

Open the expense form in its own tab rather than in a modal window inside another page.

03

The account is on the free plan

Autofill belongs to Pro. On the free plan each field has a copy button next to it.

04

The page is not a supported form

The panel matches field labels. On a form it does not recognise it says so instead of guessing, and the copy buttons still work.

Quick checks

  • The extension is pinned and the panel is open
  • The accounting tab is the active tab
  • The document shows a vendor and a total

Questions that follow

Can I map fields myself?
Yes. Settings holds a mapping profile per site, and a profile you save is used the next time that site is open.
