Fantastic - thanks IMP : Worked perfectly.

I added in 'bm_add', and ended up with this

draw_set_blend_mode_ext(bm_one, bm_zero);
//draw rectangle
draw_set_blend_mode(bm_add);
//draw text
draw_set_blend_mode(bm_normal);

Thank you all : Topic solved

Sorry about the bump Nocturn :/

IMP is right, the alpha for the text drawn on the surface is being averaged out, which causes it to become more transparent than expected. Solving this requires the use of blend modes:

mysurface = surface_create(300, 10);
surface_set_target(mysurface);
draw_set_blend_ext(bm_one, bm_dest_color);
draw_text_color(0, 0, "TEST A", c_red, c_red, c_red, c_red, 0.8);
draw_set_blend(bm_normal);
surface_reset_target();

The bm_one in the source makes sure that the destination colour is not changed, which also encapsulates IMP's idea that the surface needed to have an alpha of 1.

Fantastic! Works perfectly
That solves one of my problems at least..

[EDIT]

Nevermind : Got the second one figured out.
Thanks to everyone who helped! Much, much appreciated

Not quite the answers I was looking for.. Thanks for trying to help though.

In the draw event, I have this :

draw_text_color(x,y,"TEST A",c_red,c_red,c_red,c_red,0.8);
draw_surface_ext(mysurface,x,y+50,1,1,0,-1,1)
