Struggling with Coding

else if (event.value == "Get_furniture")

this.getField("Text3").display = display.hidden;
)
else if (event.value == "Get_housing_assistance")
(
this.getField("Text3").display = display.hidden;)
)
else if (event.value == "Get_internet_access")
(
this.getField("Text3").display = display.hidden;)

(
this.getField("Text3").display = display.hidden;)

this.getField("Text3").display = display.hidden;)

Any help would be appreciated.
