Every multiplier is valid only one time during the contest. So if you worked for example 5B4AIT on 15 m, you can work with him on others bands, but multiplier 5B4 for 5B4AIT will be counting only once during the contest. Also you will receive 1 multiplier for Cyprus. So QSO with 5B4AIT will bring you 1 multiplier for prefix and 1 multiplier for country, totally 2 points for multipliers.

Note, that only confirmed QSOs will be valid. Do not forget about 15 minutes rule. 15 minutes must have passed before you can contact the same op on a different band.
