Need a formula to:

vlookup TL-Lookup find the age if <50 than the max contribution is 18,500, if >= 50 max is 24,500
vlookup TL_Lookup trad Method, if "Gross Pay" Rate*Annual Hours*(Trad Amt/100). If trad method = "Default" pay periods*Trad Amt = Trad Contribution Amount
vlookup TL_Lookup Roth Method, if "Gross Pay" Rate*Annual Hours*(Roth Amt/100). If Roth method = "Default" pay periods*Roth Amt = Roth Contribution Amount

Total Contribution = Trad Contribution + Roth Contribution

Thanks,
