Trying to execute a script on rb750

I am using winbox on a routerboard 750up v6.30.2, which has been reset to factory settings. No scripts seem to execute,doesnt matter how simple they are. So i login to the routerboard, goto SYSTEM then SCRIPTS. I create a new script, copy one of the simple scripts into the SOURCE field, click APPLY then OK and then RUN SCRIPT, but nothing happens, except 1 is added to the RUN COUNT. Here are 2 examples i copied into the script field to create simple queue. So i am hoping someone can help me , especially if I am doing something really stupid here.

:for i from=26 to=100 do={/queue simple add target-address=(192.168.168. . $i . “/32”) max-limit=384000/768000 burst-limit=768000/1024000 burst-threshold=768000/768000 burst-time=15/15}


:for i from=2 to=51 do={/queue simple add name=“192.168.20.$i” target-address=“192.168.20.$i/32” max-limit=“64000/128000” parent=Night-User time=19h-7h,sun,mon,tue,wed,thu,fri}

Since RouterOS v6 target-addresses and interface parameters are joined into one
target parameter.

This script should work


{
:for i from=26 to=100 do={/queue simple add target=(“192.168.168.”.$i.“/32”) max-limit=384000/768000 burst-limit=768000/1024000 burst-threshold=768000/768000 burst-time=15/15}
}

Thanks PaulsMT, that worked, so least I know that scripting works. The examples i been looking at must be for older versions of RouterOS, so is there any guides that I can read so I can learn the new changes in v6.

Also is there anyone on here that writes scripts for a small fee, as I need 2 simple scripts written,if i cant manage to learn it myself :
(1) to limit download to 5gb per day and to slow bandwidth once it reaches that.
(2) to use load balance on it from 2 dls lines, with 70% from one and 30% from the other.
