2 things: With the spacebar down, your adding 1 to ChargeTime every tick the spacebars down, this will mean the ChargeTime variable fly's up very quickly and your code is set to less than/equal to 60, so chances are the variables going to be above 60 and not call the next code. Looks like it should be more than/equal to 60.
Secondly, assuming the spacebar is released and the ChargeTime variable is over/under the correct value, the Gizbot should spawn the laser - is the laser spawning under the gisbot sprite? It could be on a different layer. You'd then need to add Laser On Created and set the angle etc you want it to fire at. Bullet speed could also be set to zero.
Have a look with the debug tool open and see if it's spawning
