Please enter only the first three letters of the exhibitor's name in the field "Name".
In the field "Stand" the designation of the aisle (only one letter) will do to list all exhibitors in this aisle. For example: You are looking for the company of stand no 13A55. Select hall 13 in the field "Hall" and enter "A55" or only "A" in the field "Stand".
If the stand drawing of the chosen exhibitor is not shown, you probably have found a co-exhibitor. Search again for "hall" and "stand number" - you will find the drawing by one of the listed exhibitors.
