I have a risk register created in excel that has a tab named "lists". There are lookup formulas in the risk register that references data in the "lists" tab. Since smartsheet won't let me make tabs to my Register, how can I make the copied formula work.
Here is an example of the formula:
=IF($D4="","",AVERAGE(VLOOKUP($D4,Lists!$K$1:$S$6,9,0),(VLOOKUP($E4,Lists!$L$1:$S$6,8,0))))
I have attached .png files of the register, and the lists
