Using two formulas for one cell

Good Afternoon, 

I have been trying to figure out how to use the IF function for my problem, but I am having an impossible time.

I am trying to create an excel spreadsheet for my job. Depending on what type of evaluation I need to do, depends on how long I have to do it. If it's a new evaluation, I have 55 days to complete it, but 80 if its a renewal.  I have a column for the date of my meetings, a column that computes when my evaluation will be due, and a column that counts down the days I have left to complete it. 

For the column that computes when my evaluation is due, I want it to calculate the number of days based on the type of evaluation- ER stands for New and RR stands for a renewal.

My current formula is as follows : =[@[Re-Eval Meeting]]+80=(IF([@TYPE]="ER",[@[Re-Eval Meeting]]+55))

It comes up saying "FALSE". How Do I fix this so that it will Calculate my meeting date based on the Type column? Any help would be wonderful!
