Running Total

[twildone]

Hi....I having problem getting the output I want when it comes to calculating "Total". I would like to only sum up the "ShowAmount" if the "Start" date is missing. Any suggestions.....Thanks.

data Have;
    length ID 8 TransDate $ 8 ShowAmount 8 Date $ 8 start $ 8 end $ 8;
    format ID best12. TransDate $char8. ShowAmount DOLLAR20.2 Date $char8. start $char8. end $char8.;
	infile datalines4 dlm='7F'x missover dsd;
    input ID : best32. TransDate : $char8. ShowAmount : best32. Date : $char8. start : $char8. end : $char8. ;
datalines4;

It looks like you're doing summaries at different levels? PROC MEANS does this automatically as long as you specify your TYPES/WAYS correctly. I would recommend looking into that option instead.
