Variable name in variable name

[balala]

In a skin I have a variable First and other two variables Variable1 and Variable2. The possible values for First are 1 or 2. How can be used the Variable1 or Variable2, according to the value of First? I mean, that I'd like to have a #Variable1# or #Variable2#, according to value of First. I tried something like #Variable#First## or #Variable(#First#)#, but had no success.
Thanks

something like:

Code: Select all

[boooo]
Measure=String
String=#First#
RegExpSubstitute=1
Substitute="^1$":"#Variable1#","^2$":"#Variable2#"
