I am using ActiveState 5.8.8 Build819, which is latest available on ActiveState.

I have created a Graphics interface using Tk and try to use excel sheet in the program. I am getting the filename and row and column to process using the interface...

i used $Sheet->Cells($row,$coltag)->{'Value'} to access a cell but it is showing error. It is working fine if Tk is not used. Error displayed is-

Tk::Error: Can't use an undefined value as a HASH reference at Generat
+e_traceabi
lity_matrix1.pl line 66.
 Tk callback for .button1
 Tk::__ANON__ at C:/Perl/lib/Tk.pm line 252
 Tk::Button::butUp at C:/Perl/lib/Tk/Button.pm line 111
 <ButtonRelease-1>
 (command bound to event)

If I change $coltag variable with actual value then it works fine.

I feel that latest version do not allow both arguments in Cells() to be variable.

If this is the reason, Please suggest some alternative
