while and if statement failing

[[evo] dan 79]

Hello all. I have written this piece of code that seemingly does not work (and I cannot figure out whats wrong with it):

nm = 1;
	tskObj1 = player createSimpleTask["Primary: Patrol"]; 
	tskObj1 setSimpleTaskDescription["Patrol along the given route.", "Patrol", "Patrol"];
	sleep 4;

_triggeram1 = createTrigger["EmptyDetector",[3500,3500,0]];
_triggeram1 setTriggerArea [160,160,0,false];
_triggeram1 setTriggerActivation ["BRAVO","PRESENT",false];
_triggeram1 setTriggerTimeout [1,1,1,true];
_triggeram1 setTriggerStatements ["this", "dude = 1; publicVariable 'dude'; player setVariable ['dude', dude, TRUE];", "hint 'trigger off'"];
_Marker3 = createMarker ["Marker3", [3500,3500]]; 
"Marker3" setMarkerShape "RECTANGLE";
"Marker3" setMarkerSize [50,50];


while{nm == 1} do {
ar5 = player getVariable ["dude", 0];
sleep 10;
hint 'working';
if(ar5 == 1) then {
	hint "You've done it right";
	nm = 0;
	numberOfSites = 1;
	if(isServer) then {
	ambushSite = 2 + (round random (numberOfSites-1));
	publicVariable "ambushSite";
	player setVariable ["ambushSite", ambushSite, TRUE];
	}; 
	wait 5;
	hint 'loading';
	execVM "missions.sqf";
};
};

However, once I remove the if(isServer) part so that it looks like the below, it does work:

nm = 1;
	tskObj1 = player createSimpleTask["Primary: Patrol"]; 
	tskObj1 setSimpleTaskDescription["Patrol along the given route.", "Patrol", "Patrol"];
	sleep 4;

_triggeram1 = createTrigger["EmptyDetector",[3500,3500,0]];
_triggeram1 setTriggerArea [160,160,0,false];
_triggeram1 setTriggerActivation ["BRAVO","PRESENT",false];
_triggeram1 setTriggerTimeout [1,1,1,true];
_triggeram1 setTriggerStatements ["this", "dude = 1; publicVariable 'dude'; player setVariable ['dude', dude, TRUE];", "hint 'trigger off'"];
_Marker3 = createMarker ["Marker3", [3500,3500]]; 
"Marker3" setMarkerShape "RECTANGLE";
"Marker3" setMarkerSize [50,50];


while{nm == 1} do {
ar5 = player getVariable ["dude", 0];
sleep 10;
hint 'working';
if(ar5 == 1) then {
	hint "You've done it right";
	nm = 0;
};
};

So can someone tell me where I am going wrong with this code when going adding the extra statement?

[Double Doppler 10]

Is "wait" a valid SQF command? I have never seen it used before.

[Horner 13]

Instead of "Wait" use "Sleep". Not even sure "Wait" is a valid command like Doppler said.

Yup, my derp, changed wait to sleep and it worked fine (mixing up languages again)
