Overwrite value from LFO

Hi all,

I'm trying to build a Synth in MaxMSP. In my Synth I have a filter (biquad~), which can be modulated by an LFO.

This does work fine, however, when I try to manipulate the Filter Frequency manually, I cannot overwrite the value from the LFO, even though the LFO is not sending anything, as it is turned off.

See picture below:

Can someone tell me, how I can fix this, so I can overwrite the value in the filter frequency using the slider (that is currently set at 7700)?

Thanks very much!
