Hi evryone ,
I'm back again with my queries to seek enlightenment from this forum. I'm trying to read an excel file and parse the values, meanwhile perform checks and display values. I have written the code and while executing it, i'm able to print the values in the command prompt using the command

print "$cell->value()";
[download]

Everything works perfectly in the command prompt workspace. Now comes the problem.

I'm also using perl Tk to create a user interface to display values that do not meet checks. But when i try to print this value on to the text area by using the command :

$txt->insert('end',"$worksheet->{Cells}[$row][$col]->{Val}");
[download]

it does seem to perform the checks on the numeric values correctly, but it does not print the actual name of the corresponding value(eg Name1, name2,etc as in the below eg). The excel file is in this format:
1. Name1 1 2 40
2. Name2 45 7 6
..
What should i do ??/
PS: i tried running both the print options simultaneously and i could observe the value on the command prompt but not on the text window .. help ..!!

Another thing i noticed is that this script seems to run fine on smaller files (worksheets with less rows) .... It displays all data in text area as i expect but acts weirdly for larger files
