I’m trying to link data from a table’s dataset to a table in Report Viewer (to be saved as PDF and/or emailed). I’ve created a custom dataset for the report viewer component, and everything populates correctly. However, when attempting to link some of the keys (type float with attribute suffix “%” in cell update), I get “Error Parsing KeyChain” warning and “” as the value?

Solved, no special characters in table headers are allowed.
