Multiplication question

I am embarrassed that I am having an issue with this, but for some reason, the solution is escaping me.
I have a variable in a Design that grabs 2 data fields and multiplies them together. The output is expressed as Currency. Here is the expression:

=curtostr(strtocur(@(1,42,44)) * strtocur(@(62,99,110)))

What I wish to do is eliminate the first data pull and simply take HALF (or 50%) of the second data pull @62,99,110.

I seem to be having issues with the string statements (or at least I think that is where my errors lie.

=curtostr(strtocur(@(62,99,110))/2)
