Need an average of a range.

[Ryan1996]

I need to create an average of the range below into the top box however due to the cells being both numbers and text it doesn't seem to let me use =AVERAGE()

Can anyone help me get the average of my range to show into the top box. See below for range and cells.
[TABLE="width: 500"]
<tbody>[TR]
[TD][/TD]
[TD]H[/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD](Formula to go here)[/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD][TABLE="width: 132"]
<tbody>[TR]
[TD]1 - Very Inadequate / Major Non-Conformity[/TD]
[/TR]
</tbody>[/TABLE]
[/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD][TABLE="width: 132"]
<tbody>[TR]
[TD]2 - Inadequate / Minor Non-Conformity (high severity)[/TD]
[/TR]
</tbody>[/TABLE]
[/TD]
[/TR]
[TR]
[TD]4[/TD]
[TD][TABLE="width: 132"]
<tbody>[TR]
[TD]3 - Partially adequate / Minor Non-Conformity (low severity)[/TD]
[/TR]
</tbody>[/TABLE]
[/TD]
[/TR]
[TR]
[TD]5[/TD]
[TD][TABLE="width: 132"]
<tbody>[TR]
[TD]3 - Partially adequate / Minor Non-Conformity (low severity)[/TD]
[/TR]
</tbody>[/TABLE]
[/TD]
[/TR]
[TR]
[TD]6[/TD]
[TD][TABLE="width: 132"]
<tbody>[TR]
[TD]3 - Partially adequate / Minor Non-Conformity (low severity)[/TD]
[/TR]
</tbody>[/TABLE]
[/TD]
[/TR]
</tbody>[/TABLE]
Obviously the average is 3 here however i need to a formula to automatically do this for the whole column based on specific cells. If someone could help me with the first one i can set it up for the rest.

modification:

=SUM(IFERROR(--MID(H$2:H$1000,1,IFERROR(SEARCH(" ",H$2:H1000),0)-1),0))/COUNTA(H$2:H$1000)
