depends on how your time spent field is set up, if it is a combo box and it's just a list of values you would use something like the ON EXIT property of your time spent field
Code:
if TIMESPENT = "4 or more hours" then 'You would substitute your actual text label here
TIMESPENTEXTRA.visible = true
else
TIMESPENTEXTRA = null
TIMESPENTEXTRA.visible = false
endif
where TIMESPENTEXTRA is the name of your field you want to toggle visibility on. Just make sure you clear the value out if it exists already.
if your time spent is a calculated value it depends on how it's stored, if it's a decimal then it would be something like
Code:
if TIMESPENT >= 4 then 'You would substitute your actual text label here
TIMESPENTEXTRA.visible = true
else
TIMESPENTEXTRA = null
TIMESPENTEXTRA.visible = false
endif
and so on, you would have to modify this if you were storing the time spent as a date/time value or if you were pulling the timespent from a table with a unique identifer and you wanted pull the text string of an unbound column you would use TIMESPENT.column(x) where x would be the 0 index based column number from your combo box (in access all list boxes/combo boxes start with column 0, so your second column is actually column(1)).
