Question

I am trying to use the substring method in VTL as mentioned below

#set ($Score = $row.getValue("Score").substring(0,$row.getValue("Score").length()-1))

but it says

    Encountered "-1" at 
Was expecting one of:
   "," ...
   ")" ...
   <WHITESPACE> ...
   <DOT> ...

Please help me in resolving this issue.

Thanks

Answer 1

#set( $value = $row.getValue("Score") )
#set( $len = $value.length() - 1 )
#set( $Score = $value.substring(0, $len))

or, if you are using VelocityTools, you can do this ugly thing:

#set( $Score = $row.getValue("Score").substring(0, $math.sub($row.getValue("Score").length(), 1) )
