Hi TB Community!

I am trying to create a mortgage calculator

I look online and apparently the formula for a monthly mortgage payment is as such:

M = P [ i(1 + i)^n ] / [ (1 + i)^n –1]

**Where:**

M: is the monthly payment

P: is the loan amount

i: is the interest rate (divided by 12)

n: is the number of monthly payments (so if 30 years, then 360 (30x12))

**Using my own variables - here is what I entered:**

**The snippet is giving me this error:**

I really appreciate any guidance on how I should correctly enter the mortgage payment calculation so that TB understands it / any sample snippets
