What ileney said, but a few more thoughts.

What kind of torch are you trying to use (other than the blow torch)? And does it work with the blow torch?
What kind of flux are you using? I can't imagine it not bubbling if it's any of the standard jeweler's fluxes (Handy, Pripp's, Rio, cupronil...)
Have you considered trying to heat from below if you're having trouble heating from above? You can place a screen over an opening between two blocks and try from underneath. Still, make sure your torch keeps moving.
Make sure that the solder stays right next to the join...24gauge sheet is not very thick and can tend to distort under heat which could make the solder roll away from the join.

Good luck from me too.
