Error in SAPScript

Hi,

I have developed a custom sapscript. Its running fine via tcode FBL5N.

After the form is displayed when we are presing back we are getting a warning that :

IN FORM ZABC IN MAIN WINDOW TEST ELEMENT 510 IS MISSING.

No such text element was initially made by me. But after getting this warning, I have inserted a line (/E 510) in sapscript main window.

But still the warning log is being shown.

Please let me know how I can get rid of this.

Thanks in advance.

Regards,

Elena
