Power AWK - compare $0 to regular expression + variable

Hi,

I have this script:
Code:
awk -v va=45 '$0~va{print}' flo2

That returns: "4526745 1234 " (this is the only line of the file "flo2".

However, I would like to get "va" to match the begining of the line, so that is "va" is different than 45 (eg. 67, 12 ...) I would not have any output. That would be something like that:
Code:
awk -v va=45 '$0~/^${va}/{print}' flo2

but that does not work because $va is not a regular expression!

Any suggestion?

Thanks
