Copy multiple cell contents to another cell, IF a condition is met

Hi everyone.

Sorry if this is a simple question, but this formula has defeated a colleague and I....and we have no idea what to try next!

Basically, I have a table of employment circumstances. From the responses, I have added two columns on the end which performs some basic validation e.g flag if the respondent has said if they employed and unemployed. A simplified version of my data is below -

ID	Employment	Unemployed	Further study	Unemployed and working,	Unemployed and further study,	Errors
Person 1	Yes	Yes	No	TRUE	FALSE
Person 2	No	Yes	Yes	FALSE	TRUE
Person 3	No	Yes	No	FALSE	FALSE
Person 4	Yes	Yes	Yes	TRUE	TRUE

What I am now wanting to do is, where there is a TRUE in the validation columns, is to copy the column heading into the 'Errors' column - simply to provided a summary of the errors within the data. For example I need "Unemployed and working, Unemployed and further study," in the 'Errors' column for Person 4. As seen below.....

Desired outcome

ID	Employment	Unemployed	Further study	Unemployed and working,	Unemployed and further study,	Errors
Person 4	Yes	Yes	Yes	TRUE	TRUE	Unemployed and working, Unemployed and further study

Any help would be greatly appreciated!

Many thanks
