Switching to Datasheet view in Sharepoint

[Godders199]

Hello, I have been searching the internet , but unable to find the answer... I have a sharepoint list which displays perfectly in Standard view, if i try and switch to Datasheet view , I just get a blank grid.

I have asked colleagues to try and they get the normal excel/access grid format with all the information shown.

Is there something in sharepoint i might have ticked or deselected in error to prevent this working for me.

Thanks
