Multiple selection parameters with TDP iSeries connection

I am using Toad Data Point 3.4.0.2038. Using an iSeries database connection I have created an SQL to select data from a table. I want to use multiple parameters for the data selection. My problem is that I am able to use 1 parameter fine but if I try to use more than 1, the select does not return data. I can use 1 parameter and hard code the second select and it will work. Example: Select * from Filename where field1 = : parm1 and field2 =:parm2 does not work. When I run the SQL it prompts me for the two values but does not return data.  If I use:  Select * from Filename where field1 = :parm1 and field2 = ‘Somevalue’,  I get prompted for the first parameter and it returns the correct information using both comparisons. I have no issues using multiple parameters with an Oracle connection.  Is there something special about using the iSeries?
