Error -27257: Pending web_reg_save_param/reg_find/create_html_param[_ex] request(s)

Hi,

I am trying to read in an integer from a web service response message. I am trying to print in the log to verify that it is reading in the correct value but I am getting the following error:

Error -27257: Pending web_reg_save_param/reg_find/create_html_param[_ex] request(s) detected and reset at the end of iteration number 1      [MsgId: MERR-27257]

  The response contains:

<externalId>5651-AS</externalId>

This is the code I am using within the script:

web_reg_save_param("NumberId", "LB=</externalId>", "RB=-AS</externalId>","ORD=1", LAST);

lr_log_message(" ID Number is :" , "{NumberId}", LAST);

Any help is greatly appreciated!

Thanks in advance!
