Trouble Using a Switch and If Statement Together

[Anonymous]

I'm having trouble using the Switch and If statements together and hoping someone can help. I have a text field that is populated with data from a SP list called 'Hours Cross Charged' and the column name varies based on the month selected (thus the switch statement--shown below).

Switch(
SelectedMonth,
"January", LookUp('Hours Cross Charged', Name=User().FullName && Text(Project.Value)=Text(ProjectName_1), 'January Notes'),
"February", LookUp('Hours Cross Charged', Name=User().FullName && Text(Project.Value)=Text(ProjectName_1), 'February Notes'),
"March", LookUp('Hours Cross Charged', Name=User().FullName && Text(Project.Value)=Text(ProjectName_1), 'March Notes')
)

However, some of these fields will be blank, and those are returning the text "false." In order to remove that text and have them populated with nothing, or just hint text, I've been attempting to use an IF statement after this Switch statement. But PowerApps is finding an error at the semicolon that I put after the Switch statement's closing parenthesis there, regardless of how I'm formatting my If. 

Switch(
SelectedMonth,
"January", LookUp('Hours Cross Charged', Name=User().FullName && Text(Project.Value)=Text(ProjectName_1), 'January Notes'),
"February", LookUp('Hours Cross Charged', Name=User().FullName && Text(Project.Value)=Text(ProjectName_1), 'February Notes'),
"March", LookUp('Hours Cross Charged', Name=User().FullName && Text(Project.Value)=Text(ProjectName_1), 'March Notes')
);
If(
IsBlank(TextInput_Notes.Text), " ", " ")

Surely it's something simple that I'm overcomplicating... does anyone have any suggestions on how to combine these two?

You can use the Coalesce function that will replace the blank value with the value that you want:

Coalesce(
    Switch(
        SelectedMonth,
        "January", LookUp('Hours Cross Charged', Name=User().FullName && Text(Project.Value)= Text(ProjectName_1), 'January Notes'),
        "February", LookUp('Hours Cross Charged', Name=User().FullName && Text(Project.Value) = Text(ProjectName_1), 'February Notes'),
        "March", LookUp('Hours Cross Charged', Name=User().FullName && Text(Project.Value) = Text(ProjectName_1), 'March Notes')
    ),
    "")

Hope this helps!
