Sequential Cluster Prediction Query

Question

I'm trying to use the SSAS Sequence Cluster model and I'm struggling with creating the code to predict future sequences. In the provided code below, I'm attempting to process new data through the model I developed, and I get the following error:

Error (Data mining): An argument that is not valid is used in the PREDICTSEQUENCE function at line 2, column 19.

I'd really like to use this model but I keep getting stuck in my efforts to generate predictions.

Thanks.
