I'm tryig to use two different MAKE_ICON functions in the same file. I'm making a vor gauge so I have two sets of icons:1-BMP_V1_NO_SIGNAL - 0x0590 BMP_V1_TO_FLAG - 0x0591 BMP_V1_FROM_FLAG - 0x05922-BMP_V1_NO_GS - 0x0600 BMP_V1_GS - 0x0601I can get each set of these to work separately, but when i combine them FS won't even start. Has anyone else tried to use 2 MAKE_ICONS before?MAKE_ICON( flags_gs_vor1_icon, BMP_V1_NO_GS, NULL, NULL, IMAGE_USE_ERASE | IMAGE_USE_TRANSPARENCY, 0, 189, 131, MODULE_VAR_NONE, flag_gs_v1_cb, ICON_SWITCH_TYPE_STEP_TO, 2, 0, 0 ) PELEMENT_HEADER flags_gs_vor1_icon_list[] ={ (PELEMENT_HEADER)&flags_gs_vor1_icon, NULL};MAKE_ICON( flags_vor1_icon, BMP_V1_NO_SIGNAL, NULL, &flags_gs_vor1_icon_list, IMAGE_USE_ERASE | IMAGE_USE_TRANSPARENCY, 0, 137, 206, MODULE_VAR_NONE, flag_vor1_cb, ICON_SWITCH_TYPE_STEP_TO, 3, 0, 0 ) PELEMENT_HEADER flags_vor1_icon_list[] ={ (PELEMENT_HEADER)&flags_vor1_icon, NULL};Thanks for any help.

You have your pointer to the next element in the wrong place.it should look like this:....flags_vor1_icon,BMP_V1_NO_SIGNAL,&flags_gs_vor1_icon_list,:-waveNULL,IMAGE_USE_ERASE | IMAGE_USE_TRANSPARENCY,......before NULL not after itRegardsJim

I spent all day yesterday trying to figure that out.Jim looks at it for 30 seconds and sees the problem.That's what I love about programming.Thanks Jim

In addition, you don't need the cast (which is old style and deprecated anyway).Here's a good template for you with comments.[PRE]#pragma region MAKE_ICONMAKE_ICON( govSwitch_icon, // Name BMP_SWITCH_GOVERNOR_CENTER, // Res_ID NULL, // Next list GovSwitch_fail, // Failure IMAGE_USE_TRANSPARENCY | IMAGE_USE_ERASE, 0, // ASI Flags 0, 0, // panel ROTOR_GOV_SWITCH_POS, GovSwitch_icb, // Sourc_var, callback ICON_SWITCH_TYPE_SET_CUR_ICON, // Switch type 3, // Number of icons 0, // Scale: 0-16384 => 0-100% 0 // Offset: icon = offset-(value/scale))PELEMENT_HEADER govSwitch_next[] = { &govSwitch_icon.header, NULL };#pragma endregion /*GOVERNOR*/[/PRE]Of course, in your case the next element in the first macro would not be NULL.
