hi ,
im trying to create flow but am unsure if im getting the syntax correct here

I get the following error when I run the flow
"The expression "Booking-Ref eq 39" is not valid. Creating query failed."
this is a calculated column as my original had spaces in , but i also received the same error when i put _x0020_ in place of the space of the original Column .
I have also tried single quotes around the dynamic content which gives the same result
