Probably that you're trying to compare a string to a number.

heres the code that its saying this about:
if global.poweredup= false
{
if global.dir='up' {sprite_index=spr_links_sword_up_start; depth=1}
if global.dir='down' {sprite_index=spr_links_sword_down_start; depth=-1}
if global.dir='left' {sprite_index=spr_links_sword_left_start; depth=-1}
if global.dir='right' {sprite_index=spr_links_sword_right_start; depth=-1}
}

if global.poweredup= true
{
if global.dir='up' {sprite_index=spr_links_sword_up_power; depth=1}
if global.dir='down' {sprite_index=spr_links_sword_down_power; depth=-1}
if global.dir='left' {sprite_index=spr_links_sword_left_power; depth=-1}
if global.dir='right' {sprite_index=spr_links_sword_right_power; depth=-1}
}

{

if global.dir='down' {sprite_index=spr_links_sword_down_power; depth=-1}
if global.dir='left' {sprite_index=spr_links_sword_left_power; depth=-1}
if global.dir='right' {sprite_index=spr_links_sword_right_power; depth=-1}
}


Well then the thing to know is if global.poweredup is a string or global.dir is a number.

Actually, which line of code is it giving the error for?

The variable "direction" is a built-ion local variable represented by a number. 0 is pointing right, 90 is up, and so on. You are trying to compare that number to a string. It doesn't work that way. You must either change the checks to look for numbers, or declare the variable as a string in the first place.

Or just make sure that global.dir is declared in a Create event, or earlier in the game.

Wait, is global.dir also set to direction.

If it is then its a number 0-360, not a word left/right/up/down.

0='right'
90='up'
180='left'
270='down'
