Hi all, we are already defining a expression rule by using a doforeach ex

Am sending you the error EVAL:@reason=Invalid lexer symbol found (&)

Try this one.

Nope, EVAL:@reason=Invalid lexer symbol found (_) ;(

I can't really debug further without being able to run the code. What I've given you is syntactically correct and so should run fine unless you're calling it is some strange way; it looks like maybe this is in a portal report rather than a dashboard? What I suggest you do is take the code and run it separately in a rule to check that it works, replacing pv!ContractDetails.Contract_Serial_Number throughout with a valid serial number for testing.

When I even pass with a value without calling a Pv it genereated the same error :
error EVAL:@reason=Invalid lexer symbol found (&)

The strange thing is when I just redefine by using apply when there is a multiple version it generate the following error:
Could not process expression function. Process Id 536875556; Expression: =concatenate("

",if(count(rule!Display_Harm_Details_CDT(pv!ContractDetails.Contract_Serial_Number)),"

Maybe it will give you an idea that I shall do. As I can see doforeach() do something more that apply could not do, but am not aware what is , that is why I share it on forum and ask for help.
Thanks for your commitment to help me.

I just solve it I change the Contract SN with Version and put the version as first variable and now it works.
Thanks for your time and help.

The error tells you exactly what you need to know; the second parameter for the apply() function is expected to be the array that you wish to loop over. Your first parameter is not an array and so it doesn't work. If you wish to loop over the second parameter, then either the order of the rule inputs must change or you must use partial evaluation, as I've sent.

No problem!
