Below is the setup for my variable. It is placed in the OnSelect of a combo box called "chsHorizRequire" drop down

Set(varHorizontalDatum,(If(
chsHorizRequire.Selected.Value = "City Datum",
"CityDatumDescr",
If(
chsHorizRequire.Selected.Value = "Previous Project Coordinates",
"PreviousProjectCoordinatesDescr",
If(
chsHorizRequire.Selected.Value = "Other",
"OtherHorizontalDatumDescr",
""
)
)
)));

Below is my patch funciton

Patch(SurveyRequest_DB, Defaults(SurveyRequest_DB), { varHorizontalDatum: chsHorizRequire.Selected } )

Placing the "varHorizontalDatum" is throwing the error in the patch function.

You can't use a variable as a fieldname in a record. The fieldnames need to be literal.

Edit. Didn't realize you were making the field name a variable, like previous poster said that isn't possbile

@colbyturybury If SurveyRequest_DB is the data source that u'r patching, where varHorizontalDatum is you need to replace it with the column that your patching. You can't have a variable. For example, if I'm patching an Employee List, the Patch would be,
Patch(Employee_DB, Defaults(Employee_DB), { Emp_ID: "1", Emp_Name:" John Doe", Emp_Title:"Director" } )
