Re: [xsl] assigned variable value is changing

[Ganesh Babu N <nbabuganesh@xxxxxxxxx>]

Hai,

In the Name attribute i am capturing column number: row number.

Check the row[2]. In that we are having only 2 <entry>s instead of 3
because of the colspan.
So in my output i am increasing the column number of the 2nd <entry>
by the colspan value.

so for 2nd entry the value of @Name  is 2:1

Up to here the code is working correctly. after that in the column
number i am getting NaN. Even though i have included test conditions.

Regards,
Ganesh
