it retrieves values from below text
<input type=”text” name=”code” size=”5″ maxlength=”5″>
<input type=”text” name=”Description” size=”55″>
<input type=”text” name=”DrAmount” size=”12″ >
<input type=”text” name=”CrAmount” size=”12″”>
<input type=”text” name=”type” size=”12″”>
and this rows is increased for entering data..and its values like that..
Each time when adding a new row, the names are “incremented” following the pattern
1st row
name=”code”
name=”Description”
name=”DrAmount”
name=”DrAmount”
name=”CrAmount”
name=”type”
2nd row – new created
name=”code_1″
name=”Description_1″
name=”DrAmount_1″
name=”DrAmount_1″
name=”CrAmount_1″
name=”type_1″
3rd row – new created
name=”code_1″
name=”Description_1″
name=”DrAmount_1″
name=”DrAmount_1″
name=”CrAmount_1″
name=”type_1″
