Why does Golang expect a right bracket in the middle of a for loop?

When I try and run my Go test file, I get some errors.

This is the test file:

package rb_database

import (
    "system"
    "testing"
    "time"
)

func TestGetBinContentsResult(t *testing.T) {

    errCount := 0

    currentTime := time.Now()

    gbcr := new(getBinContentsResult)
    ids := make([]system.ID, 5, 5)

    for i := 0; i < 5; i++ {
        ids[i] = system.GenerateNewID()
    }

    copy(gbcr.deletedIds, ids)
    gbcr.earliestRecordDeletedDate = currentTime

    //Test functions
    for j := 0; j < len(gbcr.DeletedIDs()); j++ {
        if gbcr.DeletedIDs()[j] != ids[j] {
            t.Error("Element " + j + " in ID array not equal to value set. Expected Value: " + ids[j] + ". Actual Value: " + gbcr.DeletedIDs()[j])
            t.Fail()
            errCount++
        }
    }

    if gbcr.EarliestRecordDeletedDate() != currentTime {
        t.Error("Earliest record time not equal to value set. Expected Value: " + currentTime + ". Actual Value: " + gbcr.EarliestRecordDeletedDate())
        t.Fail()
        errCount++
    }

    if t.Failed() {
        t.Log("Test failed: TestGetBinContentsResult. " + errCount + "/6 possible errors occured.")
    } else {
        t.Log("Test passed: TestGetBinContentsResult. ")
    }

}

I'm using LiteIDE 27.1 and Go 1.3.3. I have made sure my GOPATH and GOROOT are set to my project directory and the Go install directory respectively.

The build output when I run TestAll is:

C:/Go/bin/go.exe test -v [C:/Users/Adam/workspace/RedboltMarch/src/rb_database]
# rb_database
get_updated_result_test.go:18:9: expected ')', found ':='
get_updated_result_test.go:49:2: expected '}', found 'EOF'
FAIL    rb_database [setup failed]
Error: process exited with code 1.

When I build and run the program normally:

C:/Go/bin/go.exe build -i [C:/Users/Adam/workspace/RedboltMarch/src/rb_database]
Success: process exited with code 0.
rb_database  [C:/Users/Adam/workspace/RedboltMarch/src/rb_database]
