It looks myVar is of string type. You have to typecast it to integer. <dtml-call "REQUEST.set('myVar','1')"> <dtml-let temp="_.int(REQUEST.myVar) + 1"> <dtml-var temp> </dtml-let> --- Tommy Johnson <tommy@7x.com> wrote:

Hello All,

Tell me if I'm missing something. I can write

<dtml-let temp="1 + 1"> and then use <dtml-var temp> to get the value 2.

Then why can't I use a variable and increment it using <dtml-let> ?

<dtml-let temp="REQEUST.myVar + 1">

I get an error : Error Type: TypeError Error Value: illegal argument type for built-in operation

The variable has the value of 1, so it should just add 1 an' 1 to give me 2. Correct, yes/no?

Thanks in advance, Tommy
