HOW do i check a value in serverscriptscriptservice then act upon it when a goal has been reached?

ok in serverscriptservice I have a script called "SVAL" "That's the name of the script". InSide is a Child named "script Value"

the value of that scriptvalue is 100 [which is an intvalue]

I made a button and when clicked I want it to see if the value of script value is greater then 50 then is it will make the button disaper

BUT...... the value of the "scriptvalue" inside the "SVAL"..... IN SERVERSCRIPTSERVICE

and that MEANS I don't have accses to all the server things IN A LOCAL SCRIPT

how can I click the button and then if the value is over 50 then it will make the button disappear...

NOTE:THE VALUE OF "scriptvalue" IS INSIDE SVAL WHICH IS IN SERVERSCRIPTSERVICE (WHICH ANYTHING LOCAL CANT, CANNOT, AND WILL NOT REACH OR ACSSES)
