Linear Regression

[tee777]

Model seems to work fine when I have 11 predictor variables...but when i increase to 12 it gives me all these error messages. 

Have checked data is all numeric so don't understand why it's limited to 11 variables as this is not a limit that is defined as per the lin reg. tool. 

Thanks

Does that extra variable have nulls?

@PhilipMannering no NULLS as I've used the imputation tool!
