Count items with a certain value using a measure but return 0 if no value exists

Hi,

I have what I hope is an easy problem - I have a table with a column 'Skill Achieved'. The data is either 'Skill Achieved' or 'Skill Gap' based on a conditional statement on the individual results.

I created a measure that counts all the value of 'Skill Achieved' in a table as shown:

This works great except it does not return a zero if the skill is not achieved by anyone as shown below 

just gives a blank in 'Num Achieved Skill' Is there a way around this? 

NOTE: I do not want to show the 'Total Num of Results' measure in my report, so with just the 'Num Achieve Skill' column, many of my skills are omitted (which I do not want..)

I hope this is clear.

Thanks in advance for your help. 

M
