Okay,
So I am trying to integrate the following code:
`Private Sub UserForm_Initialize()
Dim Fname As String
Call SaveChart
Fname = ThisWorkbook.Path & "\temp1.gif"
Me.Image1.Picture = LoadPicture(Fname)
End Sub
Private Sub SaveChart()
Dim MyChart As Chart
Dim Fname As String
Set MyChart = Sheets("Data").ChartObjects(1).Chart
Fname = ThisWorkbook.Path & "\temp1.gif"
MyChart.Export Filename:=Fname, FilterName:="GIF"
End Sub`
from this post: Displaying "live" chart data in Excel Userform into an existing loop so that the above section of code iterates with the loop and the image is updated every time the loop executes. I would have posted this as a comment on the above mentioned question, but I do not have enough rep.

Exit Sub
ErrorHandler:

UpdateLogStatus ""
End Sub'
However whenever I do this I get a Runtime Error 1004 that is built by the error handler. Any help on why this is not working is much appreciated.
EDIT: After walking away for 24 hours, I realized that the sheet in question is a chart sheet, and not an embedded chart, therefore the method I was attempting to use above was not working.
The chart is on a chart sheet called PerfMap, but the chart name is Chart 7.
