Creating expression using variable in script

[ArjunPrasad]

Hi All,

I am trying to create one expression in script using Let or Set variable but not getting expected output.

i a have a master calendar Year field 

Set vSales = 'Sum({<Year={"$(=Max(Year))"}>}SalesAmount)';

Above expression not working, applied in table expression like : $(vSales)

Set vSales = 'Sum({<Year={1998}>}SalesAmount)';  // This is working

not able figured it out , please suggest me.

Thanks

Arjun

One way could be using LET, like:

Let vSales = 'Sum({<Year={'&'"$'&'(=Max(Year))"}>}SalesAmount)';

Thank u Tresesco its working now.😊

but why we using like  { '&'"$'&'(=Max(Year))"}

cant we use like this {"$(=Max(Year))"}  //its not giving any value either.

Can you please let me know.

Thanks,

Arjun

Short answer, '$' gets evaluated in the script as well. Therefore, you have to suggest qlik engine that '$' for this case is not for expansion but treat it as a string/char.
