Mistake in Arabic PCC request letter

[AVR]

I have received PCC request letter in Arabic from London Visa office. I suppose to fill my name, nationality and passport number and take stamp from Ministry of Foreign Affairs and then submit to police head quarters in Riyadh. But, I made mistake while filling the nationality, instead of mentioning nationality I wrote passport number. However, I didn't make any corrections,  just beside I wrote nationality,  will Ministry of Foreign Affairs or Police Head Quarters refuse to take the PCC request letter, I afraid so much.   please any one give me valuable suggestions.
