Get Previous record from Running Total

I am using CR 2013. My Goal is to isolate for any records where a formula was reset based on a running total calc. I wanted to apply a formula that said 'when value in previous row is greater than value in current row, exclude, else include. Below in bold is the record I am trying to isolate for:
EeID     #RTotal             Formula           
1234     1,851.34     1,851.34          
1234     1,924.54     1,924.54          
1234     1,998.49     1,998.49          
1234     2,071.59     2,071.59          
1234     2,132.69     52.69     Display this record

I've tried the following formula:
If previous({@Formula}) > {@Formula} then "Exclude" which gives the following error message: "This field has no previous or next value".
Any other suggestions on how to isolate for the reset record would be great. Thanks!

You cannot do a previous on a formula. Records only.  It sounds you may need a variable (or two) to store the previous row value.  Then use it for comparison purposes and displaying the result.
