Error importing qif files from Capitalone

[Rob Hymns]

I'm just getting started on Gnucash and having entered some transactions
manually, I thought I'd try to import from my Capitalone credit card's
webpage.
Downloaded the qif file ok but after following the import procedure, I got a
few lines with characters converted but with the final the error message:
"Transaction amount: Unrecognized or inconsistent format."
Anyone familiar with this or got some suggestions?
