What did I do wrong for the wiring materials to be wrong?

Brite Ideas, Inc., mass-produces reading lamps. Materials used in constructing the body of the lamp are added at the start of the process, while the materials used in wiring the lamps are added at the halfway point. All labor and overhead are added en throughout the manufacturing process. Brite Ideas uses process costing and had the following unit production information available for the months of June and July. In June, the lamps in beginning work in process were approximately 90 percent complete, while those in ending work in process were only 30 percent complete. In July, the units remaining in ending work in process were 80 percent complete. All lamps in ending work in process are finished during the next month. Required: a. For the month of June, calculate the equivalent units of production for the three major cost categories-body materials, wiring materials, and labor and overhead. b. For the month of July, calculate the equivalent units of production for the three major cost categories-body materials, wiring materials, and labor and overhead. Answer is complete but not entirely correct
