I have Made sales invoice with column containing Bundles. This column has format like 48*10+1*5 [$BasicNumPackages] etc. the below code works properly. However if by mistake if one enters 48*10+ then Tally crashes as bad formula because this field is Evaluated to fill the batch Quantity or In case of Sales Invoice compare the evaluation with Qty column. What should i do to let not tally crash with bad formula, if input is like 48+ etc and just wait for valid input. Please help.
