I have an intake form where we receive campaign budgets. We are trying to track when our campaigns as a whole start spending over our expected Overall Budget. I need a column formula that can calculate the remaining budget when a new campaign is added. Currently, the intake form is set up to have new campaigns be added at the top.
Below is a screenshot of an Excel version of this where the budget cell is just =[new budget] - [previous remaining budget] and the first row (CPN-1) is =[overall budget] - [campaign budget CPN-1]
Any formulas I saw that were similar included excel functions like ROW or OFFSET which Smartsheet doesn't have. I would love any advice or recommendations on how to solve this!
