Crystal Reports: One field - multiple names

I have a table called SOURCE_EXTID for external ID's and their types. The two fields I'm trying to use are ID and TYPE.  

One sample that comes in can have multiple ID types and values. When the techs enter the info on the sample, the have a drop down list to choose as many types as they need eg. Ear Tag, Brand, Patient Ext. ID, QA Number, Name, etc.
So, my SOURCE_EXTID.type can have one, none, or multiple values that I then need to match up to the actual ID.

On my report, i have two groups from other tables FOLDERNO which gives me the case number that sample is in and then ORDNO which gives me that specific sample info.
Now I need to create multiple columns, specifically where SOURCE_EXTID.TYPE = 25 (name) and one for SOURCE_EXTID.TYPE = 26 (QA Name) and then show it's matching ID's.

I created a formula for one of them that looks like this:
IF {SOURCE_EXTID.TYPE} = 25 THEN {SOURCE_EXTID.ID} ELSE " "

thinking it would show it but it's just staring at me completely blank.  I've placed it on the group header, the footer, and I get nothing. I thought about adding a crosstab but this is going to be exported to Excel so I can't have too much formatting going on.

Any ideas?
