Dear all,

First I hope this message finds you well. I am very new to STATA and  
have something important to be done until this evening. Hence, I am  
tried quite a lot of commands, but was not successful unfortunately.

What I have to do here is the following:
1) Take the issue 31532 from v1, sum up the v116 value of each input of v115.
2) Build a new variable (e.g. v300) for each v115 and sum up v116  
according to the input (e.g. otype_t1) of v115.

As an example, the following should demonstrate:
v1	v300 (o_t3 sum of v116)		v301 (o_t3 sum of v117)
31712	5.9				25.39

I hope this is somehow clear and I would appreciate a response and  
help very much!

Thanks for everthing and have a good day,
Abdullah
