well, now i modified it again, to make it more understandable for me and for stata.
foreach `x' of ger_ims bel_ims chin_ims usa_ims uk_ims it_ims switz_ims {
2. ge foreignbrd*=`X'*(*brd)
3. }
invalid syntax
r(198);
I want it to create values containing the product of import share and R&D stock (=foreignbrd) of each country for each year.
Is that understandable? I 'm a little confused.
