Unable to add funds

I’ve opened an account and unable to add funds. When i add cash from whichever opton and it says must be at least but doesn’t say what at least. I enter in random figures from £100 to over £10,000 but won’t allow me to continue and is just grayed out. Any advice if i am doing anything wrong?
