Ok, what I'm trying to do is make this spreadsheet for money savings. When the box, named "computer savings" reaches a certain amount I want it to say Buy Memory! (Yes...I'm saving up for more memory for my computer) and just say Memory when it's less than the amount. I have this part (see formula)

=IF(AND(Q3>=120,Q3<=175),"Buy Memory!","Memory")

It works just fine.

Now, when I input the amount that it actually costs it deducts from the total amount from "computer savings". That also works just fine.

What I'm having trouble formulating is that when the amount is deducted from "computer savings" re-reaches the amount that I've defined it switches from just "Memory" (where I want it to stay) back to "Buy Memory". I don't want to buy more memory...

Sorry if this is a little confusing. I will try to better explain if I need to.
Thanks
