I am not too sure what you are trying to do, but i will try to answer based on my understanding.
I believe you are trying to parameterize your test request which would accept 2 parameters from the two columns in your excel sheet.
And you have 3 sets of data in 3 rows. If this is what you want to do, then you can create property transfer step and transfer properties from row 1 to properties step which would have two properties. You would then read these from your request and then finally place a data source loop to loop through 3 rows.
If however you want to populate different nodes in your request xml with different row sets, you might want to create 3 property transfers in the same property transfer step (PT1, PT2 and PT3). These would be transfering properties to your request. The catch is, you will have to create as many number of peroperties as there are cells to populate different nodes. An easier way could be groovy.
Hope this helps.
