Excel Formula that references a table in a different worksheet

Ok, So I made a table (on worksheet 'Load Chart') that has Crane Sizes going down the left (A Column), and in Row 1 I have radius of the pick, and cells B2:AJ14 are all the weights of the picks that correspond with the size of the crane and the distance(radius) the boom extends. With that said, I need to make some sort of generator on another worksheet that will allow me to input a certain weight of a pick, and the radius that I am picking, and have it spit out the size crane I should use. Now keep in mind the sizes vary and if the table doesnt have an exact match it would have to choose a value higher, as I am guaranteed to pick a crane that can handle a certain load. SO it should reference the column (radius), pick the nearest weight (that is same or greater than) and read the corresponding crane size in column A that matches the row that the size is in. I know its much but I hope someone can help me.
