hi Alex, thanks again for your help. I am sure it will prove spot-on!
I guess it is important to mention that this will all happen in the background. The end result is a couple of pertinent graphs (all the calculations will imbedded.
So for program flow, I have an unmatched query between a times table and a task table. (each task has a host of about 11 pertinent times.)
So the first form is 1 combo box that pulls PC's from the unmatched query. After Update on this form opens my task time form, task time calulation query, and fills a couple of static controls, PC(primary key) and a date field (as dates will be crucial down the road).
Then, when the task time form opens, it will run this loop that I am trying to build. (I just realized that I should put a resume together for a government job, i have the automation made before we know the machine will run.) hahaha
At any rate... I was using the [tasktimestart] formatted as an integer, and then concatenated with "hr" to match the textbox control name.
the code is
Dim i as integer
Dim ctl as Control
Dim starttime as integer
Dim UHU as integer
Dim ComUHU as integer

Starttime= Dlookup("POSUnitHour", "qryTaskTime", "PCNumber="&Forms![frmUnitHours]![PCNumber])
UHU= Dlookup from same query-“ConUnitHours”
i= starttime
ComUHU=i+UHU

then the loop was:
for L= starttime to ComUHU
ctl=”hr”&Format(L,”00”)
ME.ctl=1
Starttime=starttime+1
Next L
End Sub

This doesn’t work, so I am going to try what you’ve got and plug it in
