Application query section 4.8

[zaynab79]

Could someone please help me urgently ? I'm completing the form and stuck at 4.8 on award reference number for my ielts certificate. Test report form number is 18 character long but the form has only 14 characters box. Is it ok to use this as reference number and write last digits outside box .
Just to clarify I had given test in 2006 and used the same results for two extensions for tier 1 g.

Thanks
