# Spotfire - Analytics Models - Error

Hi Team,

Hope this post finds you well. I use TIBCO Spotfire 7.0.1.3. When I try to run a Regression Analysis, I get the following error:

TIBCO Enterprise Runtime for R returned an error: 'Error in model.frame.formula(formula = `Var1` ~ : object "Var1" not found'. at Spotfire.Dxp.Data.DataFunctions.Executors.LocalFunctionClient.OnExecuting(FunctionClient funcClient) at Spotfire.Dxp.Data.DataFunctions.Executors.AbstractFunctionClient.d__0.MoveNext() at Spotfire.Dxp.Data.DataFunctions.Executors.SPlusFunctionExecutor.d__0.MoveNext() at Spotfire.Dxp.Data.DataFunctions.DataFunctionExecutorService.d__6.MoveNext()

Appreciate your help!

Best Regards,

Pradeep
