I am trying to create a section at the top of the projects Gantt that shows the total allocation % for each resource in each project phase and in the project overall. I need this to not double count in resource manager, but just roll up each resource's allocation % from a Phase and the project in total. I've tried adding helper columns and summary fields, but the formula always shows that it's BLOCKED. This is the formula that I've been trying to use for the total project allocation %
=SUMIF([Assigned To]:[Assigned To], "Resource Name", [Allocation%]:[Allocation%])
