The keyword 'Then' is expected after this If statement's condition
From Xojo Documentation
Error message
You neglected to type the 'Then" keyword after the Boolean condition in an If statement. To eliminate the possibility of this error, type Shift+Enter after typing
If condition
The Code Editor will then add the "Then" after the condition, add the End If statement and place the cursor in between the two.
Another shortcut is to write only the statements that meet the condition (inside the If...End if), select them, and then choose Wrap in If...End If from the Code Editor contextual menu. This will surround your statements with IF condition Then above and End If below.
