Passing variables to addStripe command

Hi All

I am facing a problem during the execution of addStripe command with the variables as its arguments.

  addStripe -block_ring_top_layer_limit M3 -max_same_layer_jog_length 4 -padcore_ring_bottom_layer_limit M1 \
+                 -set_to_set_distance 1 -stacked_via_top_layer M3 -padcore_ring_top_layer_limit M3 \
+                 -spacing 2 -merge_stripes_value 0.065 -layer M2 -block_ring_bottom_layer_limit M1 \
+                 -width 2 -area {$XMIN $YMIN $XMAX $YMAX} -nets VDD -stacked_via_bottom_layer M1

If we specify the correct co-ordinates the stripes are properly.

addStripe -block_ring_top_layer_limit M3 -max_same_layer_jog_length 4 -padcore_ring_bottom_layer_limit M1 \
+                 -set_to_set_distance 1 -stacked_via_top_layer M3 -padcore_ring_top_layer_limit M3 \
+                 -spacing 2 -merge_stripes_value 0.065 -layer M2 -block_ring_bottom_layer_limit M1 \
+                 -width 2 -area {40.76 234.78 42.76 240.78} -nets VDD -stacked_via_bottom_layer M1

But while passing those coordinates using variables ,the stripes get places all over the core area.

 I am getting the below warining:-

**WARN: (ENCPP-613):    The intersection area is insufficient to fit any cut, so no via was created.
        layer: M1 & M2, size: 2.00 x 0.03 at (33.43, 858.39)
**WARN: (ENCPP-613):    The intersection area is insufficient to fit any cut, so no via was created.
        layer: M1 & M2, size: 2.00 x 0.06 at (78.43, 572.78)
**WARN: (ENCPP-613):    The intersection area is insufficient to fit any cut, so no via was created.
        layer: M1 & M2, size: 2.00 x 0.06 at (29.43, 603.62)
 

Please help in solving this issue.
