Error labels must start or end with white spaces

I am trying to generate a simple correlation matrix - the input is nominal data which has been converted to binominal (I tried all parameter settings). The process fails at the input or immediate processing of the correlation matrix. Any suggestions on what this error means?

@michaelgloven I would see if the Trim operator can help you out here, it removes trailing and leading whitespaces.

good suggestion, this resolved the issue...

 

and thanks, you just saved me a lot of time mucking with data...

Hi @michaelgloven,

 

I was not able to reproduce your error with this process using samples data : 

Maybe the problem come from your data : Can you share your dataset or an extract of it (if it is not sensitive)

 

Regards,

thanks for taking a look, unfortunately I cannot share the data. I'm curious what this error means, I'd think there are documented conditions which cause error? Nonetheless, since your process works I probably have something going on with my data...
