I would like to know how to accept two values

I have one table that you enter a Date select a Value (selected from a drop down menu with 3 options) a number field, and an action (memo field) which is entered



*Stdnumber is a separate table on the form that loads on start up as hidden

if the value = 1 and number is less than Stdnumber1 i want it to show the action field. else not show

but if the value is = 2 cancel out first option
and if the value = 2 and number is less than a Stdnumber2 i want it to show the action field. else not show
