Some data transfered into SPSS as 0E-9 or 0E-10 and shows in the toolbar writing space as .0 - could this be a problem?

I'm not including string data in the analysis. The warning I get follows:

Warnings

There are fewer than two cases, at least one of the variables has zero variance, there is only one variable in the analysis, or correlation coefficients could not be computed for all pairs of variables. No further statistics will be computed.

Again, I've used descriptive statistics to identify variables w/zero variance and eliminate them from my analysis.

Suggestions on getting around this problem are appreciated.

Thanks
