Match data from 3 columns to return data from the correct 4th column

[klwilliams13wf]

Hi there! I'm trying to have a cell auto-populate the data in a cell based on the data entered in 3 other cells. I've pasted a copy of the spreadsheet I'm working with below. I want to manually enter a number in C4, and in E4, and then pick a number from a drop down box in G4, and have it auto-populate the corresponding lbs/sq ft in N4 based on a chart on another worksheet. I've pasted a copy of the chart below as well. Is this possible??

That's right, although you don't need this twice

(Lists!$N$3:$N$136=I2)
