Shell balance sheet

Can someone explain to me how you get total asset and total liability figures.

The closest I can get is adding up the total figures (sub totals) + (current totals). This doesn’t give me an exact match to the number in T212 but as close as I can get

I’m stumped, sorry if this sounds stupid but I can’t work it out.

Thanks

This totals 232billion compared to T212s figure of 217billion.

If I take off the deferred income tax I get even closer.
