Unable to evaluate web_reg_save_param_ex parameter with constructed param name

$

Hello, Friends,

I have a puzzle I cannot solve.  I want to evaluate parameters created with web_reg_save_param_ex( ) using parameter names I've "constructed" in sprintf or lr_param_sprintf( ):

  • using web_reg_save_param_ex( ) with "ParamName=ErrorMessage" and "Ordinal=all" flags, the usual parameters are created.
  • so I get ErrorMessage_count=3, ErrorMessage_1=error1, ErrorMessage_2=error2, ErrorMessage_3=error3.
  • I want to print the value of each parameter, but I don't know how many errors there will be in each test run, so I don't want to hard-code something like lr_error_message("Error 1 is: %s", lr_eval_string("{ErrorMessage_1}"));
  • however, this works fine, the result will say "Error 1 is: error1
  • I've "constructed" a new parameter in a loop, one for each error, such aslr_param_sprintf("ErrorMessage_number", "ErrorMessage_%d", j ); where j changes with each iteration of the loop.  This works fine.
  • so in loop 1, lr_eval_string("{ErrorMessage_number}") evaluates to ErrorMessage_1, in loop 2, lr_eval_string("{ErrorMessage_number}") evaluates to ErrorMessage_2, etc.
  • now the puzzle - I'm unable to evaluate those constructed parameters.  Ultimately I want to print them out in an error message, likelr_error_message("error %i is %s", j, lr_eval_string("{ErrorMessage_number}"));
  • I know the above example will evaluate to "error 1 is ErrorMessage_1" but I've tried a hundred different variations, and still cannot get it to give me "error 1 is error1", "error 2 is error2", etc.
  • no matter what I do, I get the parameter name instead of the value of the parameter in the message.
  • logically it seems this should work, but it does not: lr_error_message("error %i is %s", j, lr_eval_string(lr_eval_string("{ErrorMessage_number}")))
  • even this example prints "error 2 is ErrorMessage_2"

If you have the trick I need to get this to work, it will be a very Happy New Year!

Thanks
