This is also posted on unmet hours, but I know there are a lot of folks who follow this list that aren't on unmet hours. Thanks in advance for the help.

I am trying to create a set of bi-quadratic curves for a series counter flow chiller branch using the Cool Tools spreadsheet. I have entered all the data, but I am getting a Run Time Error '13': Type Mismatch when I click create regression models.

I did have to modify the entering temp CWST to match the performance data. I didn't think that would affect the curve fit though. Does anyone know how to resolve this error? I'm not familiar enough with the underlying VBA to troubleshoot it very far. I would be glad to send the spreadsheet for anyone willing to take a look.
