@euler. The radius fields must have some value. If you have Null Values you can, do a few different aproaches. 1 - remove the point from analysis; 2- set a value of 0 or a very small value; 3 - Estimate the missing values interpolating them from the adjacent ones. It really depends on the data you have and where the Null values are.

@euler I have noew realized that you are a new to QGIS. When I mentioned using spatialite, I was referring to use SQL statments to preform the analysis, and not only storing the data in spatialite (Tho this is also good!). "spatial" SQL it's not as easy as pressing buttons but It is a very powerful tool to learn. But maybe it's better to learn the basics before. I If are willing to have a go with SQL, I can expand my answer.

comment Why is the data missing in my new shapefile?
Using 1.8 you have two options, Save Selection as... or Save as... the second option will "export" all your features/rows. QGIS 1.8 is a bit old, lot's of features and performance improvements have been added in later versions. I strongly advice you to request your IT team for an update.

comment How to calculate percentages using QGIS field calculator expression?
And don't forget to use the IN Operator. «"RVM_CAT" = 'B' OR "RVM_CAT" = 'C'» is the same as «"RVM_CAT" IN ('B','C')».
