Limits to nesting IF formula

[Hall]

Is there a limit to how many nested IF formulas can be used?

I have 11 cases I need to test for a cell but I seem to be hitting error
conditions after about 8 and the error message is generic.

Thanks

You are allowed 7

you can use a lookup function after that,
