Welcome back Heather.
Please try this formula in cell C2 of your Intake sheet.
=INDEX(Essentialskill,MATCH(C$1,INDEX(Essentialskill,0,1),0),B2+2)
Note that I made changes to your validation drop-down in B2 and some other changes in your workbook which I have marked in the attached copy of the same. The validation list you have in 'Essential Skill'!J:J won't work. I have replaced it with 'Essential Skill'!C1:G1 after first making sure that the values there correspond to what you need (all explained in the attached). The point here is that B2+2 in the above formula in fact refers to row 1 of the range Essentialskill where the first two columns are not used for this purpose. Level 1 is in column 3, hence the +2.
