One thing to bear in mind -
When you fly a procedure or are vectored for the ILS the plan is always to intercept the glidepath from below and to allow a period of level flight between establishing on the localiser & descending with the glidepath.
Therefore, as you begin to intercept the localiser beam you should always be receiving a "fly up" signal (below-glidepath indication) from the glidepath.
If at this point you are not getting a below-glidepath indication check your position & range from touchdown.
