IF AND formula to work out value parameters

[NJS1982]

Hi all, I have a formula that I can't seem to get to work...

=IF(AND(Z833>=1,Z833<=14999),"£1-15,000",
IF(AND(Z833>=15000,Z833<=49999),"£15,001-49,999",
IF(Z833>=50000,"£50,000+")))

Does anyone know what I am doing wrong? Thanks!

Don't worry, I worked it out! I needed to add a if(z833=0,"") into it (was showing up as FALSE on zeron values you see). Thanks for looking!!
