I am not I totally follow your logic but you can try, Get(ActiveRepetitionNumber ).
You really should be using repeating fields in such a manner. It is structurally wrong and will most likely probably bite you one day. Repeating fields are great for utility purposes, but for true data, I would highly advise against you using them.
You could simply lookup the hourly wage into another repeating field - though I agree with mr_vodka that you should NOT use repeating fields at all in this case. There should be a separate join table for assigning employees to projects.
Also, it's not good practice to match by names - use unique ID's (serial numbers) instead.
thank you. Mr_vodka and Comment for the tip and solution.
I will look for an alternative solution to the "people involved in project" repeating field. Meanwhile, the Get(ActiveRepetitionNumber ) was exactly what I was looking for.
