iwpt_dcr_values with spaces in dct names

System

Not sure if this is an issue, I have a Perl script that is reading a dcr that has names with spaces.

For example:
$Primary = iwpt_dcr_value('CurrentDCR.Interest Rate Data.Primary Credit Rate');

Wasnt it said that that spaces in dct field names are discouraged and should include under scores such as first_name instead of first name?
(I didnt design this dct to begin with).

Is the spaces in names an issue, or is there a way in Perl to ignore the spaces in the names?

If this is not an issue, then it might be something else - need to start somewhere in my trouble shooting. First extracted value comes out fine (which is a one word dct field name), but the 2nd and 3rd values do not (which have multiple word dct field names).

Thanks
