Hi, I am trying to calculate the fees for a project based a list of fees from another sheet. My current formula works when only one product is selected but does not work for multiple products. Would converting this to INDEX/COLLECT work? And if so, how would I do it?
Current formula looks up the value in Project Type/Scope on the Project Fees sheet and brings in the value from column 3. If the number of sites is >1 it adds the value from column 4, times the number of sites minus one
(VLOOKUP([Project Type/Scope]@row, {Project Fees}, 3, false)) + (IF([Number of Sites]@row > 1, ([Number of Sites]@row - 1), 0) * VLOOKUP([Project Type/Scope]@row, {Project Fees}, 4, false))
Columns being used - formula is in estimated fees column (ignore SOW#)
Project Type/Scope is a multi select dropdown
