I have a switch function in the control source to evaluated a text field [text 173].
it is as follows

=Switch([Text173]>=3.1,1,[Text173] Between 2.8 And 3,2,[Text173]>=2.3<=2.7,3,[Text173] Between 1.9 And 2.2,4,[Text173]=0,0,[Text173]<=1.8,5)

the switch function evaluates everything except the between statements.
for example if [text173] = 1.9 it is blank.

anyone have any suggestions
