problem in passing the value to smartform

Hi,

I am new to the smartforms and i having hardly any knowledge about it.I am working on a smartform in which i am passing the value to the smartform but the problem is as i am passing the value to it by declaring it in to the global variables of the smartforms but still is not taking the value in it,

the previous value was stored in the table's main area in the cell having the different nodes and codes.

plzz provide me guidelines for solving this problem.
