Calling a Variable in Part of a Column Name Using LookUp

Hi all - 

I'm somewhat new to PowerApps and am trying to pass a variable in a column name in a LookUp function and am currently unable to figure out how to do so. I've searched these boards (perhaps I'm using the wrong search terms) but haven't seen this issue in the boards. Surely I'm not the only one with this issue?

My SP List has columns labeled 'January Week 1,' 'January Week 2,' 'January Week 3,' 'January Week 4,' 'January Week 5,' 'February Week 1,' 'February Week 2,' 'February Week 3,' 'February Week 4,' 'February Week 5,' ...and so on.

My var is SelectedMonth, and updates based on the user's selection.

 

I have a label that is successfully displaying 
          SelectedMonth & " Week 1"

 

However, I'm unable to pull the data from the SP list from that column. I currently have:
          LookUp('Hours Cross Charged', Name=User().FullName, 'January Week 1')

 

Anytime that I try to put a variable in the single quotes, under several different combinations I've tried, it gives me an error. 
What way can I tell PowerApps to retrieve the data from column 
          'SelectedMonth & " Week 1"'?

Any help is greatly appreciated!!

Unfortunately you cannot dynamically reference a column in PowerApps like this.

 

SelectedMonth & " Week 1"'?

All you can do is use a SWITCH function instead

 

Switch(
    SelectedMonth,
    "January", 'January Week1', 
    "February", 'February Week 1',
    "March", 'March Week 1'
)

I know it is possible in many PRO programming languages but not here.

Thank you for the clarification! It seems that it would make things simpler if we could type functions with variables such as this. Perhaps one day in the future. Thanks again @mdevaney

I agree, custom functions would be very nice.  You can always go submit it as an Idea and see if it catches on.
