Write reg value with a variable

[msb5150]

using this code: RegWrite, REG_SZ, HKEY_CURRENT_USER, Software\\BatchD2O, D2OLoc, location

where 'location' is a variable, I am unable to write the value that I want, as with my current code 'D2OLoc' is assigned the varable 'location' instead of the value of location. What should I change?

Nevermind, I found my problem (I was using an old version, I'm now using version 3)
