Hi Folks

I'm a newbie to this forum so please go easy on me

I have an Excel sheet, and I would like to create a formula whereby the number I enter into once cell determines a text phrase in another - ie:

If I enter a number between 0.001 and 0.249 in cell F2, then in cell B2 the phrase 'class7' is input. If i enter a number between 0.250 and 0.499, the in cell B2 the phrase class6 is input - and so on.....

Any help would be greatly appreciated, I'm no beginner but I certainly aint no expert!

Kind Regards
Mark
