Greater Than symbol not being accepted as valid.

Hi,

I'm working on a table to determine when an Organization first enrolled for any of our services. This could be for a Portal service which there is a Training Record for or a Data connection for which there is Interface Record. I've been able to pull back the earliest date from each table to determine when the first service was.

Here is the expression I'm using:

         Case
         When  Min(Trn."Training Date - End Users")  >= Min(InterS."Go Live Date")  >= Min(InterD."Go Live Date") Then Min(Trn."Training Date - End Users")
         When Min(Trn."Training Date - End Users") >=Min(InterD."Go Live Date") >=Min(InterS."Go Live Date")  Then Min(Trn."Training Date - End Users")
         When Min(InterS."Go Live Date")>= Min(InterD."Go Live Date") >= Min(Trn."Training Date - End Users") Then Min(InterS."Go Live Date")
         When Min(InterS."Go Live Date")>= Min(Trn."Training Date - End Users")>=Min(InterD."Go Live Date") Then   Min(InterS."Go Live Date")
         When Min(InterD."Go Live Date")>= Min(InterS."Go Live Date")>=Min(Trn."Training Date - End Users") Then Min(InterD."Go Live Date")
         When Min(InterD."Go Live Date")>= Min(Trn."Training Date - End Users")>=Min(InterS."Go Live Date") Then Min(InterD."Go Live Date")
         END as "Initial Participation Date"

I've used case statement like this before and it works. 

This is the error I'm getting:
Parsing of SQL query failed. Please check the SQL syntax.

Some tips:
Parse error at line 35, column 85.  Encountered: >

My only thought is it's not reading those columns as valid number type columns but as text and so the >= is not valid for text?


THe original Column is in the correct Date format:
