# Troubleshooting

## "No exchange rate on file"

The invoice used a rate of 1 because no rate exists for that currency on or before the invoice date. [Add the rate](/docs/exchange-rates), then edit and re-save the invoice.

## The bank account list is empty

There's no account for the invoice's company **and** currency that was open on the invoice date. Add one under **Companies → Banks**, or check the invoice date.

## No LUT is selected

The company has no LUT in force on the invoice date. [Add the LUT](/docs/luts) for that financial year.

## "Worth checking: the declaration claims export under LUT…"

The invoice is under an LUT, but some lines carry GST. Under an LUT, export lines should be 0%.

## I can't see a page my colleague can

Pages follow your role. Ask an administrator to check your role under **Administration → Roles**.

## "Your session expired"

Sign in again. Sessions also end at once if your account is disabled, moved to another organisation, or your organisation is suspended.
