You need to check what ROUNDDOWN($AA$1/$A11^D$37,0) evaluates to. It
needs to be a number between 1 and 65536. If it is likely not to be a
number you'll need to put some error checking in it and decide what you want
the value to be if there is an error.

Does this not work when there's a text command in the equation

I'm inputting =INDIRECT("B" & ROUNDDOWN($AA$1/$A11^D$37,0))

(all listed cells exist)

and it shows an error...
