Formula scripting changes automatically - How to correct this issue?

Formula scripting changes automatically - How to correct this issue?

Hey guys I'm having an issue here and it's not with my math (I'm pretty sure...). The issue is I need this formula:


((New_Rent_Amount  +  Car_Payments  +  Insurance_Payments  +  Credit_Card_Payments  +  Loan_Payments  +  Other_Obligations)  /  (Monthly_Gross_Household_Income)) * (33.33)


But after hitting 'Done' (it allows me to do it), it automatically changes to this:


((New_Rent_Amount  +  Car_Payments  +  Insurance_Payments  +  Credit_Card_Payments  +  Loan_Payments  +  Other_Obligations)  /  Monthly_Gross_Household_Income  *  33.33)


Any thoughts/ideas? Thanks in advance to all!
