Forms :: Making Textbox Visible On A Form If Checkbox Is Checked On Same Form

I am having a problem with making a textbox visible on a form if a checkbox is checked on the same form. I have done research on this site and have written the code below, but I am getting a Syntax error, see yellow highlight.

- My checkbox is named: Case is a Readmission from WRCA IP to WRCA IP
- My textbox is named: Date of Current IP Admission (I have defaulted this textbox to not visible).

Here's the code I have written:

Private Sub Case_is_a_Readmission_from_WRCA_IP_to_WRCA_IP_Clic k()
If Case is a Readmission from WRCA IP to WRCA IP =true then
Date of Current IP Admission.visible=true
Else
Date of Current IP Admission.visible=false
