Runner bean flower setting

Question

I grew White Lady Runner beans in my greenhouse last year (much too windy to grow outside up here in the N. W. ). The flowers refused to set initially in the earlier part of the season, but later I achieved a fantastic crop. This year I have ‘loads of flowers’ but there is no sign of setting. Help.
