ooh man! i thought, only dumb ppl come to sajha. guess i was wrong. :D highvoltage - u nailed it (y) I guess, when u state the problem verbally then i reckon the confussion starts and its really hard to figure out the mis-calculation which i did. But, in the case of sajha - i had to write up the problem. Anywayz, ANY ONE FROM UMASS, Pennstate or U. Maryland??? or, anyone who knows ppl who goes there. thanks in advance.
